All Implemented Interfaces:

PickMapper

public class ParityManager

extends IdManager

Manages the membership of graphic views in "parity groups" to achieve consistent interaction feedback across views. The members of a parity group represent different client models that should be equal in the context of interaction feedback. For example, a given line of source code in a list view and the corresponding vertices in a call graph should appear selected, together.

The members of the aspect models registered with this manager are assigned to mutually exclusive interactor groups associated with parity model client IDs. A pick mapper maps target interactors to parity groups according to the target client ID. As such, this manager should be used just after the unity manager in the picking chain.

Monitors aspect model activity (see AspectModel.getAspectModelMonitor()) to automatically update parity groups. Note that parity groups will only be created automatically for aspect models that are of type ParityModel.

Constructor Detail

ParityManager

public ParityManager(IdManager target)

Creates an instance as the mapper after the target mapper in a picking chain.

Parameters:

target - The target manager. Never null.

Method Detail

addGroup

public final void addGroup(AspectModel aspect)

Adds an aspect model to this manager as a parity group. Ignored if the aspect is already registered. Throws an exception if an aspect member is already in a diferent parity group.

removeGroup

public final void removeGroup(AspectModel aspect)

Removes an aspect model from this manager as a parity group. Ignored if the aspect is not registered.

addGraphic

public final void addGraphic(GraphicView view)

removeGraphic

public final void removeGraphic(GraphicView view)
