  • Method Details

    • commitTimestampInMillis

      public final Long commitTimestampInMillis()

      The time at which the commit for the transaction was requested, in milliseconds from the Unix epoch.

      Returns:
      The time at which the commit for the transaction was requested, in milliseconds from the Unix epoch.

    • hasEventId

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

    • eventId

      public final Map<String,String> eventId()

      The sequence identifier of the stream change record.

      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 hasEventId() method.

      Returns:
      The sequence identifier of the stream change record.

    • data

      public final SparqlData data()

      The serialized SPARQL change record. The serialization formats of each record are described in more detail in Serialization Formats in Neptune Streams.

      Returns:
      The serialized SPARQL change record. The serialization formats of each record are described in more detail in Serialization Formats in Neptune Streams.

    • op

      public final String op()

      The operation that created the change.

      Returns:
      The operation that created the change.

    • isLastOp

      public final Boolean isLastOp()

      Only present if this operation is the last one in its transaction. If present, it is set to true. It is useful for ensuring that an entire transaction is consumed.

      Returns:
      Only present if this operation is the last one in its transaction. If present, it is set to true. It is useful for ensuring that an entire transaction is consumed.

    • toBuilder

      public SparqlRecord.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<SparqlRecord.Builder,SparqlRecord>
      Returns:
      a builder for type T

    • builder

      public static SparqlRecord.Builder builder()

    • serializableBuilderClass

      public static Class<? extends SparqlRecord.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.
