Interface BatchedStateUpdatesStrategy

public interface BatchedStateUpdatesStrategy

A Batched State Update Strategy will define when do we schedule a final state update and corresponding layout calculation, so that we can enqueue the most reasonable number of state updates without incurring with an excessive number of layout calculations.

Method Summary

Modifier and Type	Method and Description
boolean	onAsyncStateUpdateEnqueued(java.lang.String attribution, boolean isCreateLayoutInProgress) This method is called whenever an async state update was enqueued and added to the StateHandler.
void	onInternalStateUpdateStart() This method is called whenever ComponentTree.updateStateInternal(boolean, String, boolean) is called.
void	release() This method should be called whenever the resources held by this strategy should be freed or reset.

Method Detail

onAsyncStateUpdateEnqueued

boolean onAsyncStateUpdateEnqueued(java.lang.String attribution,
                                   boolean isCreateLayoutInProgress)

This method is called whenever an async state update was enqueued and added to the StateHandler.

This method should return true if it is considering this update to its batching strategy; otherwise it should simply return false.

onInternalStateUpdateStart

void onInternalStateUpdateStart()

This method is called whenever ComponentTree.updateStateInternal(boolean, String, boolean) is called.

This will help the batching strategy on decide how to update its internal state by knowing that all current enqueued updates will be consumed soon.

release

void release()

This method should be called whenever the resources held by this strategy should be freed or reset.

This can be pending Runnable, state variables, etc.
