The type of change.
Constants
NO_CHANGE
value: 0
No change has occurred. Used only to send an updated resume_token
.
ADD
value: 1
The targets have been added.
REMOVE
value: 2
The targets have been removed.
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.

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
.
