Class TransformVisualOperation
java.lang.Object
org.eclipse.core.commands.operations.AbstractOperation
org.eclipse.gef.mvc.fx.operations.TransformVisualOperation
- All Implemented Interfaces:
IUndoableOperation
,ITransactionalOperation
The
TransformVisualOperation
can be used to change an Affine
,
for example, one that is contained within the transformations list of a
Node
to transform that Node
.-

TransformVisualOperation
Constructs a newTransformVisualOperation
to change the given nodeTransform.- Parameters:
transformablePart
- TheITransformableContentPart
that will be transformed by this operation.
-
TransformVisualOperation
public TransformVisualOperation(ITransformableContentPart<? extends Node> transformablePart, Affine newTransform) Constructs a newTransformVisualOperation
to change the given nodeTransform. The given newTransform will be applied to the nodeTransform upon execution of this operation.- Parameters:
transformablePart
- TheITransformableContentPart
that will be transformed by this operation.newTransform
- TheAffine
that will be set as the visual transformation for the givenITransformableContentPart
upon execution of this operation.

Method Details
-
applyTransform
Sets the visual transformation to the givenAffine
.- Parameters:
transform
- TheAffine
that is to be set as the total visual transformation for theITransformableContentPart
.

in interfaceIUndoableOperation
- Specified by:

in classAbstractOperation
- Throws:
ExecutionException
-
getInitialTransform
Returns the initialAffine
of theITransformableContentPart
.- Returns:
- The initial
Affine
of theITransformableContentPart
.
-
getNewTransform
Returns theAffine
that will be set as the transformation matrix of theITransformableContentPart
.- Returns:
- The
Affine
that will be set as the transformation matrix of theITransformableContentPart
.
-
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:

in interfaceIUndoableOperation
- Specified by:

in classAbstractOperation
- Throws:
ExecutionException
-
setFinalTransform
Sets theAffine
that will be set as the transformation matrix of theITransformableContentPart
.- Parameters:
newTransform
- TheAffine
that will be set as the transformation matrix of theITransformableContentPart
.
