          cz.cuni.amis.pogamut.base.agent.navigation.impl.PathFuture<PATH_ELEMENT>

Type Parameters:

PATH_ELEMENT -

All Implemented Interfaces:

IPathFuture<PATH_ELEMENT>, java.util.concurrent.Future<java.util.List<PATH_ELEMENT>>

Direct Known Subclasses:

UT2004AStarPathFuture

public class PathFuture<PATH_ELEMENT>
extends ComponentFuture<java.util.List<PATH_ELEMENT>>
implements IPathFuture<PATH_ELEMENT>

Simple implementation of the IPathFuture interface that assumes the computation to be dependent on some IComponents. Therefore the path future retrieval method (ComponentFuture.get() and ComponentFuture.get(long, java.util.concurrent.TimeUnit)) will fail if one of these components fails.

Field Summary

Fields inherited from class cz.cuni.amis.utils.future.FutureWithListeners

latch, listeners, mutex

Constructor Summary

PathFuture(PATH_ELEMENT pathFrom, PATH_ELEMENT pathTo)
Initialize the path future as independent on any IComponent.

PathFuture(PATH_ELEMENT pathFrom, PATH_ELEMENT pathTo, IComponentBus bus, IComponent... dependants)
Initialize the path future as dependent on 'dependants'.

Method Summary

PATH_ELEMENT	getPathFrom() Where does the path start.
PATH_ELEMENT	getPathTo() Where does the path end.

Constructor Detail

PathFuture

public PathFuture(PATH_ELEMENT pathFrom,
                  PATH_ELEMENT pathTo)

Initialize the path future as independent on any IComponent.

Parameters:

pathFrom -

pathTo -

PathFuture

public PathFuture(PATH_ELEMENT pathFrom,
                  PATH_ELEMENT pathTo,
                  IComponentBus bus,
                  IComponent... dependants)

Initialize the path future as dependent on 'dependants'. If one of the component the path computation depends on fails - the path future will report exception upon getting the path result.

See ComponentFuture.ComponentFuture(IComponentBus, IComponent...) for more details about 'bus' and 'dependants' parameters.

Parameters:

pathFrom -

pathTo -

bus -

depends -

Method Detail

getPathFrom

public PATH_ELEMENT getPathFrom()

Description copied from interface: IPathFuture

Where does the path start. Note that this point might not be the first item of the path element list, this element marks the start location from which the planner has begun.

Specified by:

getPathFrom in interface IPathFuture<PATH_ELEMENT>

Returns:

getPathTo

public PATH_ELEMENT getPathTo()

Description copied from interface: IPathFuture

Where does the path end. Note that this point might not be the last item of the path element list, this element marks the end location to which the planner should plan the path.

Specified by:

getPathTo in interface IPathFuture<PATH_ELEMENT>

Returns:
