All Implemented Interfaces:

@Generated("software.amazon.awssdk:codegen") public final class InputTransformer extends Object implements SdkPojo, Serializable, ToCopyableBuilder<InputTransformer.Builder,InputTransformer>

Contains the parameters needed for you to provide custom input to a target based on one or more pieces of data extracted from the event.

  • Method Details

    • hasInputPathsMap

      public final boolean hasInputPathsMap()
      For responses, this returns true if the service returned a value for the InputPathsMap 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.

    • inputPathsMap

      public final Map<String,String> inputPathsMap()

      Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.

      InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 100 key-value pairs. You must use JSON dot notation, not bracket notation.

      The keys cannot start with "Amazon Web Services."

      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 hasInputPathsMap() method.

      Returns:
      Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.

      The keys cannot start with "Amazon Web Services."

    • inputTemplate

      public final String inputTemplate()

      Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value> The InputTemplate must be valid JSON.

      If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

      • The placeholder cannot be used as an object key.

      The following example shows the syntax for using InputPathsMap and InputTemplate.

      "InputTransformer":

      {

      "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

      "InputTemplate": "<instance> is in state <status>"

      }

      To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:

      "InputTransformer":

      {

      "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

      "InputTemplate": "<instance> is in state \"<status>\""

      }

      The InputTemplate can also be valid JSON with varibles in quotes or out, as in the following example:

      "InputTransformer":

      {

      "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

      "InputTemplate": '{"myInstance": <instance>,"myStatus": "<instance> is in state \"<status>\""}'

      }

      Returns:
      Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value> The InputTemplate must be valid JSON.

      }

      }

    • toBuilder

      public InputTransformer.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<InputTransformer.Builder,InputTransformer>
      Returns:
      a builder for type T

    • builder

      public static InputTransformer.Builder builder()

    • serializableBuilderClass

      public static Class<? extends InputTransformer.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • 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)

    • 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.
