All Implemented Interfaces:

IPolicy, IRelationshipPolicy

public class DefaultRelationshipPolicy
extends AbstractPolicy
implements IRelationshipPolicy

The default implementation of the IRelationshipPolicy allows all timeline objects to be linked with each other and returns a DefaultCreateRelationshipCommand command object for performing the actual linking.

Since:

1.0

Constructor Summary

DefaultRelationshipPolicy()

Method Summary

ICommand	getCreateRelationshipCommand(TimelineObjectPath sourcePath, TimelineObjectPath targetPath, IGanttChartModel model) Returns a command object that will perform the actual linking of the source and target timeline objects by making the appropriate changes in the model.
boolean	isRelationshipSource(TimelineObjectPath path, IGanttChartModel model) Determines whether the given timeline object can be used for creating a relationship to another object.
boolean	isRelationshipTarget(TimelineObjectPath sourcePath, TimelineObjectPath targetPath, IGanttChartModel model) Determines whether the given source timeline object can be linked to the given target timeline object.
