public class DetachFromContentAnchorageOperation extends org.eclipse.core.commands.operations.AbstractOperation implements ITransactionalOperation
DetachFromContentAnchorageOperation
uses the IContentPart
API to detach an anchored from the given anchorage.Constructor and Description |
---|
DetachFromContentAnchorageOperation(IContentPart<? extends javafx.scene.Node> anchored,
java.lang.Object contentAnchorage,
java.lang.String role)
Creates a new
DetachFromContentAnchorageOperation to detach the
given anchored IContentPart from the given
contentAnchorage under the specified role, so that it will
not be returned by subsequent calls to
IContentPart.getContentAnchoragesUnmodifiable() . |

determine if the execution of the operation will affect the model, for
example, to set an editor's dirty flag.isContentRelevant
