public class SetRefreshVisualOperation extends AbstractOperation implements ITransactionalOperation
ASetRefreshVisualOperationis used to set/unset theIVisualPart.isRefreshVisual()flag of a specifiedIVisualPart. This can be handy to guard other operations from model refreshes.

isContentRelevant
public boolean isContentRelevant()
Description copied from interface:ITransactionalOperationReturnstrueif thisITransactionalOperationis actually changing model data (instead of only affecting the visualization). Otherwise returnsfalse.

trueif thisITransactionalOperationis actually changing model data, otherwisefalse.
