  • Method Details

    • isTruncated

      public final Boolean isTruncated()

      A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria.

      Returns:
      A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria.

    • marker

      public final String marker()

      Indicates where in the bucket listing begins. Marker is included in the response if it was sent with the request.

      Returns:
      Indicates where in the bucket listing begins. Marker is included in the response if it was sent with the request.

    • nextMarker

      public final String nextMarker()

      When the response is truncated (the IsTruncated element value in the response is true), you can use the key name in this field as the marker parameter in the subsequent request to get the next set of objects. Amazon S3 lists objects in alphabetical order.

      This element is returned only if you have the delimiter request parameter specified. If the response does not include the NextMarker element and it is truncated, you can use the value of the last Key element in the response as the marker parameter in the subsequent request to get the next set of object keys.

      Returns:
      When the response is truncated (the IsTruncated element value in the response is true), you can use the key name in this field as the marker parameter in the subsequent request to get the next set of objects. Amazon S3 lists objects in alphabetical order.

      This element is returned only if you have the delimiter request parameter specified. If the response does not include the NextMarker element and it is truncated, you can use the value of the last Key element in the response as the marker parameter in the subsequent request to get the next set of object keys.

    • hasContents

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

    • contents

      public final List<S3Object> contents()

      Metadata about each object returned.

      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 hasContents() method.

      Returns:
      Metadata about each object returned.

    • name

      public final String name()

      The bucket name.

      Returns:
      The bucket name.

    • prefix

      public final String prefix()

      Keys that begin with the indicated prefix.

      Returns:
      Keys that begin with the indicated prefix.

    • delimiter

      public final String delimiter()

      Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.

      Returns:
      Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.

    • maxKeys

      public final Integer maxKeys()

      The maximum number of keys returned in the response body.

      Returns:
      The maximum number of keys returned in the response body.

    • hasCommonPrefixes

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

    • commonPrefixes

      public final List<CommonPrefix> commonPrefixes()

      All of the keys (up to 1,000) rolled up in a common prefix count as a single return when calculating the number of returns.

      A response can contain CommonPrefixes only if you specify a delimiter.

      CommonPrefixes contains all (if there are any) keys between Prefix and the next occurrence of the string specified by the delimiter.

      CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix.

      For example, if the prefix is notes/ and the delimiter is a slash (/), as in notes/summer/july, the common prefix is notes/summer/. All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.

      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 hasCommonPrefixes() method.

      Returns:
      All of the keys (up to 1,000) rolled up in a common prefix count as a single return when calculating the number of returns.

    • encodingType

      public final EncodingType encodingType()

      Encoding type used by Amazon S3 to encode object keys in the response. If using url, non-ASCII characters used in an object's key name will be URL encoded. For example, the object test_file(3).png will appear as test_file%283%29.png.

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

      Returns:
      Encoding type used by Amazon S3 to encode object keys in the response. If using url, non-ASCII characters used in an object's key name will be URL encoded. For example, the object test_file(3).png will appear as test_file%283%29.png.

    • encodingTypeAsString

      public final String encodingTypeAsString()

      Specified by:
      toBuilder in class AwsResponse
      Returns:
      a builder for type T

    • builder

      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.

      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkResponse
      Used to retrieve the value of a field from any class that extends SdkResponse. 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 SdkResponse.getValueForField(String, Class) method will again be available.

      Optional containing the casted return value

      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
