verifyExtends static method
Throws an AssertionError if instance
does not extend
AggregateQuerySnapshotPlatform.
This is used by the app-facing AggregateQuerySnapshot
to ensure that
the object in which it's going to delegate calls has been
constructed properly.
Implementation
static void verifyExtends(AggregateQuerySnapshotPlatform instance) {
PlatformInterface.verifyToken(instance, _token);
}
