From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public void onBound (T binding)

Called after values have been reevaluated in executePendingBindings(). This is only called if all listeners have returned true from onPreBind(ViewDataBinding).

The default implementation does nothing.

Parameters

binding	The ViewDataBinding that is reevaluating its bound values.

public void onCanceled (T binding)

Called after all callbacks have completed onPreBind(ViewDataBinding) when one or more of the calls has returned false.

The default implementation does nothing.

Parameters

binding	The ViewDataBinding that is reevaluating its bound values.

public boolean onPreBind (T binding)

Called when values in a ViewDataBinding should be reevaluated. This does not mean that values will actually change, but only that something in the data model that affects the bindings has been perturbed.

Return true to allow the reevaluation to happen or false if the reevaluation should be stopped. If false is returned, it is the responsibility of the OnRebindListener implementer to explicitly call executePendingBindings().

The default implementation only returns true.

Parameters

binding	The ViewDataBinding that is reevaluating its bound values.

Returns

true to indicate that the reevaluation should continue or false to halt evaluation.
