public class FXTransformConnectionPolicy
extends FXTransformPolicy

The FXTransformConnectionPolicy is an FXTransformPolicy that is adjusted for the relocation of an Connection. It uses an FXBendOperation to update the anchors of the Connection according to the applied translation.

Method Detail

applyTransform

public void applyTransform(AffineTransform newTransform)

Description copied from class: AbstractTransformPolicy

Applies the given AffineTransform as the new transformation matrix to the host. All transformation changes are applied via this method. Therefore, subclasses can override this method to perform adjustments that are necessary for its host .

Overrides:

applyTransform in class AbstractTransformPolicy<javafx.scene.Node>

Parameters:

newTransform - The new transformation matrix for the host.

commit

public ITransactionalOperation commit()

Description copied from class: AbstractTransactionPolicy

Returns an 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.

Overrides:

commit in class AbstractTransformPolicy<javafx.scene.Node>

Returns:

An ITransactionalOperation that performs all manipulations applied by the policy since the last AbstractTransactionPolicy.init() call.

getIndicesOfMovableAnchors

protected java.util.List<java.lang.Integer> getIndicesOfMovableAnchors()

Returns the indices of all movable anchors. Only those anchors are relocated by this policy.

Returns:

List of Integers specifying the anchors to relocate.

init

public void init()

Description copied from class: AbstractTransactionPolicy

Initializes the policy, so that the policy's "work" methods can be used. Calling a "work" method while the policy is not initialized will result in an IllegalStateException. It is safe to call AbstractTransactionPolicy.init() multiple times in sequence.

Overrides:

init in class AbstractTransformPolicy<javafx.scene.Node>
