  • Method Details

    • hasLastEventId

      public final boolean hasLastEventId()
      For responses, this returns true if the service returned a value for the LastEventId 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.
    • lastEventId

      public final Map<String,String> lastEventId()

      Sequence identifier of the last change in the stream response.

      An event ID is composed of two fields: a commitNum, which identifies a transaction that changed the graph, and an opNum, which identifies a specific operation within that transaction:

      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 hasLastEventId() method.

      Returns:
      Sequence identifier of the last change in the stream response.

      An event ID is composed of two fields: a commitNum, which identifies a transaction that changed the graph, and an opNum, which identifies a specific operation within that transaction:

    • lastTrxTimestampInMillis

      public final Long lastTrxTimestampInMillis()

      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.
    • format

      public final String format()

      Serialization format for the change records being returned. Currently, the only supported value is NQUADS.

      Returns:
      Serialization format for the change records being returned. Currently, the only supported value is NQUADS.
    • hasRecords

      public final boolean hasRecords()
      For responses, this returns true if the service returned a value for the Records 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.
    • records

      public final List<SparqlRecord> records()

      An array of serialized change-log stream records included in the response.

      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 hasRecords() method.

      Returns:
      An array of serialized change-log stream records included in the response.
    • totalRecords

      public final Integer totalRecords()

      The total number of records in the response.

      Returns:
      The total number of records in the response.
    • toBuilder

      public GetSparqlStreamResponse.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<GetSparqlStreamResponse.Builder,GetSparqlStreamResponse>
      Specified by:
      toBuilder in class AwsResponse
      Returns:
      a builder for type T
    • builder

      public static GetSparqlStreamResponse.Builder builder()
    • serializableBuilderClass

      public static Class<? extends GetSparqlStreamResponse.Builder> serializableBuilderClass()
    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class AwsResponse
    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class AwsResponse
    • 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: 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.
      Overrides:
      getValueForField in class SdkResponse
      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.
    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
