Cloud Firestore V1 Client - Class Target (1.44.1)

Reference documentation and code samples for the Cloud Firestore V1 Client class Target.

A specification of a set of documents to listen to.

Generated from protobuf message google.firestore.v1.Target

Constructor.

A target specified by a query.

A target specified by a query.

A target specified by a set of document names.

A target specified by a set of document names.

A resume token from a prior TargetChange for an identical target.

Using a resume token with a different target is unsupported and may fail.

Start listening after a specific read_time .

The client must know the state of matching documents at this time.

The target ID that identifies the target on the stream. Must be a positive number and non-zero.

If target_id is 0 (or unspecified), the server will assign an ID for this target and return that in a TargetChange::ADD event. Once a target with target_id=0 is added, all subsequent targets must also have target_id=0 . If an AddTarget request with target_id != 0 is sent to the server after a target with target_id=0 is added, the server will immediately send a response with a TargetChange::Remove event. Note that if the client sends multiple AddTarget requests without an ID, the order of IDs returned in TargetChage.target_ids are undefined. Therefore, clients should provide a target ID instead of relying on the server to assign one. If target_id is non-zero, there must not be an existing active target on this stream with the same ID.

If the target should be removed once it is current and consistent.

The number of documents that last matched the query at the resume token or read time.

This value is only relevant when a resume_type is provided. This value being present and greater than zero signals that the client wants ExistenceFilter.unchanged_names to be included in the response.

Returns the unboxed value from getExpectedCount()
