TransformContentOperation
public TransformContentOperation(ITransformableContentPart<? extends Node> transformableContentPart, AffineTransform finalTransform) Creates a newTransformContentOperation
for the givenITransformableContentPart
to set the givenAffineTransform
.- Parameters:
transformableContentPart
- The part to transform.finalTransform
- The total finalAffineTransform
to set.

execute
- 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
.

redo
- Specified by:
redo
in interfaceIUndoableOperation
- Specified by:
redo
in classAbstractOperation
- Throws:
ExecutionException
-
setFinalDelta
Sets the givenAffineTransform
as the new transform to set on the content.- Parameters:
transform
- The newAffineTransform
to set.
