public final class HeartbeatRecord
extends com.google.api.client.json.GenericJson

A heartbeat record is returned as a progress indicator, when there are no data changes or any other partition record types in the change stream partition.

This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Cloud Spanner API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json

Method Detail

getTimestamp

public String getTimestamp()

Indicates the timestamp at which the query has returned all the records in the change stream partition with timestamp <= heartbeat timestamp. The heartbeat timestamp will not be the same as the timestamps of other record types in the same partition.

Returns:

value or null for none

setTimestamp

public HeartbeatRecord setTimestamp(String timestamp)

Indicates the timestamp at which the query has returned all the records in the change stream partition with timestamp <= heartbeat timestamp. The heartbeat timestamp will not be the same as the timestamps of other record types in the same partition.

Parameters:

timestamp - timestamp or null for none

set

public HeartbeatRecord set(String fieldName,
                           Object value)

Overrides:

set in class com.google.api.client.json.GenericJson

clone

public HeartbeatRecord clone()

Overrides:

clone in class com.google.api.client.json.GenericJson
