Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ target_change_type	int The type of change that occurred.
↳ target_ids	int[] The target IDs of targets that have changed. If empty, the change applies to all targets. The order of the target IDs is not defined.
↳ cause	Google\Rpc\Status The error that resulted in this change, if applicable.
↳ resume_token	string A token that can be used to resume the stream for the given target_ids, or all targets if target_ids is empty. Not set on every target change.
↳ read_time	Google\Protobuf\Timestamp The consistent read_time for the given target_ids (omitted when the target_ids are not at a consistent snapshot). The stream is guaranteed to send a read_time with target_ids empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not). For a given stream, read_time is guaranteed to be monotonically increasing.
