public class ContentBehavior<VR>
extends AbstractBehavior<VR>
implements java.beans.PropertyChangeListener, IDisposable

Method Detail

activate

public void activate()

Specified by:

activate in interface IActivatable

Overrides:

activate in class AbstractBehavior<VR>

deactivate

public void deactivate()

Specified by:

deactivate in interface IActivatable

Overrides:

deactivate in class AbstractBehavior<VR>

dispose

public void dispose()

Specified by:

dispose in interface IDisposable

disposeIfObsolete

protected void disposeIfObsolete(IContentPart<VR,? extends VR> contentPart)

If the given IContentPart does neither have a parent nor any anchoreds, then it's content is set to null and the part is added to the ContentPartPool.

Parameters:

contentPart - The IContentPart that is eventually disposed.

findOrCreatePartFor

protected IContentPart<VR,? extends VR> findOrCreatePartFor(java.lang.Object content)

Finds/Revives/Creates an IContentPart for the given content Object. If an IContentPart for the given content Object can be found in the viewer's content-part-map, then this part is returned. If an IContentPart for the given content Object is stored in the injected ContentPartPool, then this part is returned. Otherwise, the injected IContentPartFactory is used to create a new IContentPart for the given content Object.

Parameters:

content - The content Object for which the corresponding IContentPart is to be returned.

Returns:

The IContentPart corresponding to the given content Object.

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent event)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

synchronizeContentAnchorages

public void synchronizeContentAnchorages(com.google.common.collect.SetMultimap<? extends java.lang.Object,java.lang.String> contentAnchorages)

Updates the host IVisualPart's IContentPart anchorages (see IVisualPart.getAnchorages()) so that it is in sync with the set of content anchorages that is passed in.

Parameters:

contentAnchorages - * The map of content anchorages with roles to be synchronized with the list of IContentPart anchorages ( IVisualPart.getAnchorages()).

See Also:

IContentPart.getContentAnchorages(), IVisualPart.getAnchorages()

synchronizeContentChildren

public void synchronizeContentChildren(java.util.List<? extends java.lang.Object> contentChildren)

Updates the host IVisualPart's IContentPart children (see IVisualPart.getChildren()) so that it is in sync with the set of content children that is passed in.

Parameters:

contentChildren - The list of content children to be synchronized with the list of IContentPart children ( IVisualPart.getChildren()).

IContentPart.getContentChildren(), IVisualPart.getChildren()
