public class SetRefreshVisualOperation extends AbstractOperation implements ITransactionalOperation
SetRefreshVisualOperation is used to set/unset the
IVisualPart.isRefreshVisual() flag of a specified IVisualPart
. This can be handy to guard other operations from model refreshes.| Constructor and Description |
|---|
SetRefreshVisualOperation(IVisualPart<? extends javafx.scene.Node> part,
boolean from,
boolean to)
Creates a new
SetRefreshVisualOperation for setting the
IVisualPart.isRefreshVisual() flag of the given
IVisualPart to the to value on execution and to the
from value on undoing. |

Returns
true if this ITransactionalOperation is
actually changing model data (instead of only affecting the
visualization). |

isNoOp()
Returns
true if this ITransactionalOperation has no
effect (in comparison to its initial state). |

ITransactionalOperationtrue if this ITransactionalOperation is
actually changing model data (instead of only affecting the
visualization). Otherwise returns false. The content
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 in interface ITransactionalOperationtrue if this ITransactionalOperation is
