Class SyncMutator

java.lang.Object

com.twilio.sync.SyncMutator

public abstract class SyncMutator
extends java.lang.Object

Mutator is a functional object that you provide to modify entity data in a controlled manner. Override onApplied to perform your modifications. This method will be provided with the previous data contents and should return new desired contents or null to abort mutate operation. You *must* dispose() a mutator to avoid memory leaks. Internally, the native part will keep a strong reference to the Java class, keeping it from being GC'd.
