public abstract class OnRebindCallback
extends Object

java.lang.Object
↳	android.databinding.OnRebindCallback<T extends android.databinding.ViewDataBinding>

Listener set on addOnRebindCallback(OnRebindCallback) that is called when bound values must be reevaluated in executePendingBindings().

Summary

Public constructors
`OnRebindCallback()`

Public methods
`void`	`onBound(T binding)` Called after values have been reevaluated in `executePendingBindings()`.
`void`	`onCanceled(T binding)` Called after all callbacks have completed `onPreBind(ViewDataBinding)` when one or more of the calls has returned `false`.
`boolean`	`onPreBind(T binding)` Called when values in a ViewDataBinding should be reevaluated.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

OnRebindCallback ()

Public methods

onBound

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`	`T`: The ViewDataBinding that is reevaluating its bound values.

onCanceled

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`	`T`: The ViewDataBinding that is reevaluating its bound values.

onPreBind

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`	`T`: The ViewDataBinding that is reevaluating its bound values.

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