Represents the input of an UpdateItem operation.

  • Method Details

    • tableName

      public final String tableName()

      The name of the table containing the item to update. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

      Returns:
      The name of the table containing the item to update. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

    • hasKey

      public final boolean hasKey()
      For responses, this returns true if the service returned a value for the Key property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • key

      public final Map<String,AttributeValue> key()

      The primary key of the item to be updated. Each element consists of an attribute name and a value for that attribute.

      For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasKey() method.

      Returns:
      The primary key of the item to be updated. Each element consists of an attribute name and a value for that attribute.

      For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

    • hasAttributeUpdates

      public final boolean hasAttributeUpdates()
      For responses, this returns true if the service returned a value for the AttributeUpdates property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • attributeUpdates

      public final Map<String,AttributeValueUpdate> attributeUpdates()

      This is a legacy parameter. Use UpdateExpression instead. For more information, see AttributeUpdates in the Amazon DynamoDB Developer Guide.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAttributeUpdates() method.

      Returns:
      This is a legacy parameter. Use UpdateExpression instead. For more information, see AttributeUpdates in the Amazon DynamoDB Developer Guide.

    • hasExpected

      public final boolean hasExpected()
      For responses, this returns true if the service returned a value for the Expected property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • expected

      public final Map<String,ExpectedAttributeValue> expected()

      This is a legacy parameter. Use ConditionExpression instead. For more information, see Expected in the Amazon DynamoDB Developer Guide.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExpected() method.

      Returns:
      This is a legacy parameter. Use ConditionExpression instead. For more information, see Expected in the Amazon DynamoDB Developer Guide.

    • conditionalOperator

      public final ConditionalOperator conditionalOperator()

      This is a legacy parameter. Use ConditionExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.

      If the service returns an enum value that is not available in the current SDK version, conditionalOperator will return ConditionalOperator.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from conditionalOperatorAsString().

    • returnValues

      public final ReturnValue returnValues()

      Use ReturnValues if you want to get the item attributes as they appear before or after they are successfully updated. For UpdateItem, the valid values are:

      • NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)

      • ALL_OLD - Returns all of the attributes of the item, as they appeared before the UpdateItem operation.

      • UPDATED_OLD - Returns only the updated attributes, as they appeared before the UpdateItem operation.

      • ALL_NEW - Returns all of the attributes of the item, as they appear after the UpdateItem operation.

      • UPDATED_NEW - Returns only the updated attributes, as they appear after the UpdateItem operation.

      There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

    • updateExpression

      public final String updateExpression()

      An expression that defines one or more attributes to be updated, the action to be performed on them, and new values for them.

      The following action values are available for UpdateExpression.

      • SET - Adds one or more attributes and values to an item. If any of these attributes already exist, they are replaced by the new values. You can also use SET to add or subtract from an attribute that is of type Number. For example: SET myNum = myNum + :val

        SET supports the following functions:

        • if_not_exists (path, operand) - if the item does not contain an attribute at the specified path, then if_not_exists evaluates to operand; otherwise, it evaluates to path. You can use this function to avoid overwriting an attribute that may already be present in the item.

        • list_append (operand, operand) - evaluates to a list with a new element added to it. You can append the new element to the start or the end of the list by reversing the order of the operands.

        These function names are case-sensitive.

      • REMOVE - Removes one or more attributes from an item.

      • ADD - Adds the specified value to the item, if the attribute does not already exist. If the attribute does exist, then the behavior of ADD depends on the data type of the attribute:

        • If the existing attribute is a number, and if Value is also a number, then Value is mathematically added to the existing attribute. If Value is a negative number, then it is subtracted from the existing attribute.

          If you use ADD to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses 0 as the initial value.

          Similarly, if you use ADD for an existing item to increment or decrement an attribute value that doesn't exist before the update, DynamoDB uses 0 as the initial value. For example, suppose that the item you want to update doesn't have an attribute named itemcount, but you decide to ADD the number 3 to this attribute anyway. DynamoDB will create the itemcount attribute, set its initial value to 0, and finally add 3 to it. The result will be a new itemcount attribute in the item, with a value of 3.

        • If the existing data type is a set and if Value is also a set, then Value is added to the existing set. For example, if the attribute value is the set [1,2], and the ADD action specified [3], then the final attribute value is [1,2,3]. An error occurs if an ADD action is specified for a set attribute and the attribute type specified does not match the existing set type.

          Both sets must have the same primitive data type. For example, if the existing data type is a set of strings, the Value must also be a set of strings.

        The ADD action only supports Number and set data types. In addition, ADD can only be used on top-level attributes, not nested attributes.

      • DELETE - Deletes an element from a set.

        If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set [a,b,c] and the DELETE action specifies [a,c], then the final attribute value is [b]. Specifying an empty set is an error.

        The DELETE action only supports set data types. In addition, DELETE can only be used on top-level attributes, not nested attributes.

      You can have many actions in a single expression, such as the following: SET a=:value1, b=:value2 DELETE :value3, :value4, :value5

      For more information on update expressions, see Modifying Items and Attributes in the Amazon DynamoDB Developer Guide.

      Returns:
      An expression that defines one or more attributes to be updated, the action to be performed on them, and new values for them.

      The following action values are available for UpdateExpression.

      • SET - Adds one or more attributes and values to an item. If any of these attributes already exist, they are replaced by the new values. You can also use SET to add or subtract from an attribute that is of type Number. For example: SET myNum = myNum + :val

        SET supports the following functions:

        • list_append (operand, operand) - evaluates to a list with a new element added to it. You can append the new element to the start or the end of the list by reversing the order of the operands.

        These function names are case-sensitive.

      • REMOVE - Removes one or more attributes from an item.

      • ADD - Adds the specified value to the item, if the attribute does not already exist. If the attribute does exist, then the behavior of ADD depends on the data type of the attribute:

        • If the existing attribute is a number, and if Value is also a number, then Value is mathematically added to the existing attribute. If Value is a negative number, then it is subtracted from the existing attribute.

          If you use ADD to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses 0 as the initial value.

          Similarly, if you use ADD for an existing item to increment or decrement an attribute value that doesn't exist before the update, DynamoDB uses 0 as the initial value. For example, suppose that the item you want to update doesn't have an attribute named itemcount, but you decide to ADD the number 3 to this attribute anyway. DynamoDB will create the itemcount attribute, set its initial value to 0, and finally add 3 to it. The result will be a new itemcount attribute in the item, with a value of 3.

        • If the existing data type is a set and if Value is also a set, then Value is added to the existing set. For example, if the attribute value is the set [1,2], and the ADD action specified [3], then the final attribute value is [1,2,3]. An error occurs if an ADD action is specified for a set attribute and the attribute type specified does not match the existing set type.

    • conditionExpression

      public final String conditionExpression()

      A condition that must be satisfied in order for a conditional update to succeed.

      An expression can contain any of the following:

      • Functions: attribute_exists | attribute_not_exists | attribute_type | contains | begins_with | size

        These function names are case-sensitive.

      • Comparison operators: = | <> | < | > | <= | >= | BETWEEN | IN

      • Logical operators: AND | OR | NOT

      For more information about condition expressions, see Specifying Conditions in the Amazon DynamoDB Developer Guide.

      Returns:
      A condition that must be satisfied in order for a conditional update to succeed.

      An expression can contain any of the following:

      • Functions: attribute_exists | attribute_not_exists | attribute_type | contains | begins_with | size

        These function names are case-sensitive.

      • Comparison operators: = | <> | < | > | <= | >= | BETWEEN | IN

      • Logical operators: AND | OR | NOT

      For more information about condition expressions, see Specifying Conditions in the Amazon DynamoDB Developer Guide.

    • hasExpressionAttributeNames

      public final boolean hasExpressionAttributeNames()
      For responses, this returns true if the service returned a value for the ExpressionAttributeNames property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • expressionAttributeNames

      public final Map<String,String> expressionAttributeNames()

      One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

      • To access an attribute whose name conflicts with a DynamoDB reserved word.

      • To create a placeholder for repeating occurrences of an attribute name in an expression.

      • To prevent special characters in an attribute name from being misinterpreted in an expression.

      Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

      • Percentile

      The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide.) To work around this, you could specify the following for ExpressionAttributeNames:

      • {"#P":"Percentile"}

      You could then use this substitution in an expression, as in this example:

      • #P = :val

      Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

      For more information about expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExpressionAttributeNames() method.

      Returns:
      One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • expressionAttributeValues

      public final Map<String,AttributeValue> expressionAttributeValues()

      One or more values that can be substituted in an expression.

      Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the ProductStatus attribute was one of the following:

      Available | Backordered | Discontinued

      You would first need to specify ExpressionAttributeValues as follows:

      { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

      You could then use these values in an expression, such as this:

      ProductStatus IN (:avail, :back, :disc)

      For more information on expression attribute values, see Condition Expressions in the Amazon DynamoDB Developer Guide.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExpressionAttributeValues() method.

      equals in class AwsRequest

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
