Constructor Detail

ShortestPathMapBasedPoiMovement

public ShortestPathMapBasedPoiMovement(Settings settings)

Creates a new movement model based on a Settings object's settings.

Parameters:

settings - The Settings object where the settings are read from

ShortestPathMapBasedPoiMovement

protected ShortestPathMapBasedPoiMovement(ShortestPathMapBasedPoiMovement mbm)

Copyconstructor.

Parameters:

mbm - The ShortestPathMapBasedPoiMovement prototype to base the new object to

Method Detail

getPath

public Path getPath()

Description copied from class: MovementModel

Returns a new path by this movement model or null if no new path could be constructed at the moment (node should wait where it is). A new path should not be requested before the destination of the previous path has been reached.

Overrides:

getPath in class MapBasedMovement

Returns:

A new path or null

replicate

public ShortestPathMapBasedPoiMovement replicate()

Description copied from class: MovementModel

Creates a replicate of the movement model.

Overrides:

replicate in class MapBasedMovement

Returns:

A new movement model with the same settings as this model

getPois

public PointsOfInterestEvac getPois()

isReady

public boolean isReady()

Description copied from interface: SwitchableMovement

Checks if the movement model is finished doing its task and it's time to switch to the next movement model. The method should be called between getPath() calls.

Specified by:

isReady in interface SwitchableMovement

Overrides:

isReady in class MapBasedMovement

Returns:

true if ready

setHost

public void setHost(DTNHost host)

Overrides:

setHost in class MovementModel

Parameters:

host - the host to set
