Class CombinedBooleanFuture

java.lang.Object
  cz.cuni.amis.utils.future.CombinedBooleanFuture

All Implemented Interfaces:

IFuture<java.lang.Boolean>, java.util.concurrent.Future<java.lang.Boolean>

public class CombinedBooleanFuture
extends java.lang.Object
implements IFuture<java.lang.Boolean>

Used to combine multiple Future<Boolean> together into one Future<Boolean>.

During construction of the instance of this class you have to specify an array of booleans you want to combine - then all methods will wait for all futures to end (e.g. get(), etc.).

Note that you will probably want to use getAll() method to get respective Future results.

Constructor Summary

CombinedBooleanFuture(IFuture<java.lang.Boolean>[] futures)

Method Summary

boolean	cancel(boolean mayInterruptIfRunning)
java.lang.Boolean	get() Waits if necessary for the computation to complete, and then retrieves its result.
java.lang.Boolean	get(long timeout, java.util.concurrent.TimeUnit unit) Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.
java.lang.Boolean[]	getAll(long timeout, java.util.concurrent.TimeUnit unit)
java.util.concurrent.Future<java.lang.Boolean>[]	getFutures()
boolean	isCancelled()
boolean	isDone()
