AbstractBehavior

public AbstractBehavior()

Method Detail

activate

public void activate()

Specified by:

activate in interface IActivatable

addFeedback

protected void addFeedback(java.util.List<? extends IVisualPart<VR,? extends VR>> targets)

Switches to the relevant adaptable scopes ( switchAdaptableScopes()) and uses the injected IFeedbackPartFactory to create feedback parts for the given list of target parts. The resulting feedback parts are anchored to the target parts and added as children to the host's root part.

Parameters:

targets - The IVisualParts for which feedback parts should be generated.

See Also:

addFeedback(List, Map)

addFeedback

protected void addFeedback(java.util.List<? extends IVisualPart<VR,? extends VR>> targets,
                           java.util.Map<java.lang.Object,java.lang.Object> contextMap)

Switches to the relevant adaptable scopes ( switchAdaptableScopes()) and uses the injected IFeedbackPartFactory to create feedback parts for the given list of target parts and the given context map. The resulting feedback parts are anchored to the target parts and added as children to the host's root part.

Parameters:

targets - The IVisualParts for which feedback parts should be generated.

contextMap - A map containing context information for the creation of the feedback parts.

addHandles

protected void addHandles(java.util.List<? extends IVisualPart<VR,? extends VR>> targets)

Switches to the relevant adaptable scopes ( switchAdaptableScopes()) and uses the injected IHandlePartFactory to create handle parts for the given list of target parts. The resulting handle parts are anchored to the target parts and added as children to the host's root part.

Parameters:

targets - The IVisualParts for which handle parts should be generated.

See Also:

addHandles(List, Map)

addHandles

protected void addHandles(java.util.List<? extends IVisualPart<VR,? extends VR>> targets,
                          java.util.Map<java.lang.Object,java.lang.Object> contextMap)

Switches to the relevant adaptable scopes ( switchAdaptableScopes()) and uses the injected IHandlePartFactory to create handle parts for the given list of target parts and the given context map. The resulting handle parts are anchored to the target parts and added as children to the host's root part.

Parameters:

targets - The IVisualParts for which handle parts should be generated.

contextMap - A map containing context information for the creation of the handle parts.
