public class DeletionPolicy
extends AbstractPolicy

The DeletionPolicy is an AbstractPolicy that handles the deletion of content.

It handles the deletion of a IContentPart's content by initiating the removal from the content parent via the ContentPolicy of the parent IContentPart, as well as the detachment of anchored content elements via the ContentPolicys of anchored IContentParts.

This policy should be registered at an IRootPart. It depends on ContentPolicys being registered on all IContentParts that are affected by the deletion.

Method Details

createOperation

protected ITransactionalOperation createOperation()

Description copied from class: AbstractPolicy

Creates an ITransactionalOperation that is used to encapsulate the changes that are applied by this AbstractPolicy through its "work" methods. The created operation should allow for local execution at each time.

Specified by:

createOperation in class AbstractPolicy

Returns:

A new ITransactionalOperation to encapsulate all applied changes.

delete

public void delete(IContentPart<? extends javafx.scene.Node> contentPartToDelete)

Deletes the given IContentPart by removing the IContentPart's content from the parent IContentPart' content and by detaching the contents of all anchored IContentParts from the IContentPart's content.

Parameters:

contentPartToDelete - The IContentPart to mark for deletion.

getCompositeOperation

protected AbstractCompositeOperation getCompositeOperation()

Extracts a AbstractCompositeOperation from the operation created by createOperation(). The composite operation is used to combine individual content change operations.

Returns:

The AbstractCompositeOperation that is used to combine the individual content change operations.

getDeselectOperation

protected DeselectOperation getDeselectOperation()

Returns the DeselectOperation used by this DeletionPolicy to deselect the to be deleted parts.

Returns:

The DeselectOperation that is used.

getUnfocusOperation

protected ChangeFocusOperation getUnfocusOperation()

Returns the ChangeFocusOperation used by this DeletionPolicy to unfocus the to be deleted parts. .

Returns:

The ChangeFocusOperation that is used.
