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

execute
public IStatus execute(IProgressMonitor monitor, IAdaptable info) throws ExecutionException
- Specified by:
execute
in interfaceIUndoableOperation
- Specified by:
execute
in classAbstractOperation
- Throws:
ExecutionException

isContentRelevant
public boolean isContentRelevant()
Description copied from interface:ITransactionalOperation
Returnstrue
if thisITransactionalOperation
is actually changing model data (instead of only affecting the visualization). Otherwise returnsfalse
. The content relevance of anITransactionalOperation
can 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:
isContentRelevant
in interfaceITransactionalOperation
- Returns:
true
if thisITransactionalOperation
is actually changing model data, otherwisefalse
.
-
isNoOp
public boolean isNoOp()
Description copied from interface:ITransactionalOperation
Returnstrue
if thisITransactionalOperation
has no effect (in comparison to its initial state). Otherwise returnsfalse
.- Specified by:
isNoOp
in interfaceITransactionalOperation
- Returns:
true
if thisITransactionalOperation
has no effect, otherwisefalse
.
