public class AttachToContentAnchorageOperation extends AbstractOperation implements ITransactionalOperation
AttachToContentAnchorageOperation
uses the IContentPart
API to attach an anchored to the given anchorage.Constructor and Description |
---|
AttachToContentAnchorageOperation(IContentPart<? extends javafx.scene.Node> anchored,
java.lang.Object contentAnchorage,
java.lang.String role)
Creates a new
AttachToContentAnchorageOperation to attach the
given anchored IContentPart to the given
contentAnchorage under the specified role, so that it will
be returned by subsequent calls to
IContentPart.getContentAnchoragesUnmodifiable() . |

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