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.
