-
getResizablePart
public IResizableContentPart<? extends javafx.scene.Node> getResizablePart()
Returns theIResizableContentPartthat is resized by this operation.- Returns:

-
isContentRelevant
public boolean isContentRelevant()
Description copied from interface:ITransactionalOperationReturnstrueif thisITransactionalOperationis actually changing model data (instead of only affecting the visualization). Otherwise returnsfalse. The content relevance of anITransactionalOperationcan be checked to determine if the execution of the operation will affect the model, for example, to set an editor's dirty flag.- Specified by:
isContentRelevantin interfaceITransactionalOperation- Returns:
trueif thisITransactionalOperationis actually changing model data, otherwisefalse.
-
isNoOp
public boolean isNoOp()

isNoOpin interfaceITransactionalOperation- Returns:
trueif thisITransactionalOperationhas no effect, otherwisefalse.
