Constants
NO_CHANGE
Value: 0
No change has occurred. Used only to send an updated resume_token.
Generated from protobuf enum NO_CHANGE = 0;
ADD
Value: 1
The targets have been added.
Generated from protobuf enum ADD = 1;
REMOVE
Value: 2
The targets have been removed.
Generated from protobuf enum REMOVE = 2;
CURRENT
Value: 3
The targets reflect all changes committed before the targets were added
to the stream.
This will be sent after or with a read_time that is greater than or
equal to the time at which the targets were added.
Listeners can wait for this change if read-after-write semantics
are desired.
Generated from protobuf enum CURRENT = 3;
RESET
Value: 4
The targets have been reset, and a new initial state for the targets
will be returned in subsequent changes.
After the initial state is complete, CURRENT will be returned even
if the target was previously indicated to be CURRENT.
