Class GetSparqlStreamResponse

    • Method Detail

      • 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.
      • 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:
