Methods

#documents

def documents() -> ::Google::Cloud::Firestore::V1::Target::DocumentsTarget
Returns

#documents=

def documents=(value) -> ::Google::Cloud::Firestore::V1::Target::DocumentsTarget
Parameter
Returns

#expected_count

def expected_count() -> ::Google::Protobuf::Int32Value
Returns
  • (::Google::Protobuf::Int32Value) — 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.

#expected_count=

def expected_count=(value) -> ::Google::Protobuf::Int32Value
Parameter
  • value (::Google::Protobuf::Int32Value) — 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
  • (::Google::Protobuf::Int32Value) — 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.

#once

def once() -> ::Boolean
Returns
  • (::Boolean) — If the target should be removed once it is current and consistent.

#once=

def once=(value) -> ::Boolean
Parameter
  • value (::Boolean) — If the target should be removed once it is current and consistent.
Returns
  • (::Boolean) — If the target should be removed once it is current and consistent.

#query

def query() -> ::Google::Cloud::Firestore::V1::Target::QueryTarget
Returns

#query=

def query=(value) -> ::Google::Cloud::Firestore::V1::Target::QueryTarget
Parameter
Returns

#read_time

def read_time() -> ::Google::Protobuf::Timestamp
Returns
  • (::Google::Protobuf::Timestamp) — Start listening after a specific read_time.

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

#read_time=

def read_time=(value) -> ::Google::Protobuf::Timestamp
Parameter
  • value (::Google::Protobuf::Timestamp) — Start listening after a specific read_time.

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

Returns
  • (::Google::Protobuf::Timestamp) — Start listening after a specific read_time.

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

#resume_token

def resume_token() -> ::String
Returns
  • (::String) — A resume token from a prior TargetChange for an identical target.

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

#resume_token=

def resume_token=(value) -> ::String
Parameter
  • value (::String) — A resume token from a prior TargetChange for an identical target.

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

Returns
  • (::String) — A resume token from a prior TargetChange for an identical target.

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

#target_id

def target_id() -> ::Integer
Returns
  • (::Integer) — 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.

#target_id=

def target_id=(value) -> ::Integer
Parameter
  • value (::Integer) — 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.
