public class FXTransformConnectionPolicy extends FXTransformPolicy
FXTransformConnectionPolicy
is an FXTransformPolicy
that
is adjusted for the relocation of an Connection
. It uses an
FXBendConnectionOperation
to update the anchors of the
Connection
according to the applied translation.TRANSFORM_PROVIDER_KEY

ITransactionalOperation |
commit()
Returns an
ITransactionalOperation that performs all
manipulations applied by the policy since the last AbstractTransactionPolicy.init() call. |
protected ITransactionalOperation |
createOperation()
Creates an
ITransactionalOperation that is used to encapsulate
the changes that are applied by this AbstractTransactionPolicy
through its "work" methods. |
protected ITransactionalOperation |
createTransformContentOperation()
Returns an operation to transform the content.
|
protected FXBendConnectionOperation |
getBendConnectionOperation()
Returns the
FXBendConnectionOperation to be used by this policy. |

getHost()
|
protected java.util.List<java.lang.Integer> |
getIndicesOfUnconnectedAnchors()
Returns the indices of all movable anchors.
|
void |
init()
Initializes the policy, so that the policy's "work" methods can be used.
|
protected boolean |
isContentTransformable()
Returns whether the content can be transformed.
|
protected void |
updateTransformOperation(AffineTransform newTransform)
Updates the operation that was created within
AbstractTransactionPolicy.createOperation()
so that it will set the host's transformation to match
the given AffineTransform upon execution. |

AbstractTransactionPolicy
ITransactionalOperation
that performs all
manipulations applied by the policy since the last AbstractTransactionPolicy.init()
call.
When called multiple times in sequence, only the first call will yield an
operation, the subsequent calls will yield null
