public class FXRelocateConnectionPolicy
extends FXTransformPolicy

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

public FXRelocateConnectionPolicy()

Method Detail

commit

public IUndoableOperation commit()

Description copied from interface: ITransactional

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

Specified by:

commit in interface ITransactional

Overrides:

commit in class FXTransformPolicy

Returns:

An IUndoableOperation that performs all manipulations applied by the policy since the last ITransactional.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 interface: ITransactional

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 ITransactional.init() multiple times in sequence.

Specified by:

init in interface ITransactional

Overrides:

init in class FXTransformPolicy

locallyExecuteOperation

protected void locallyExecuteOperation()

Executes the current operation without pushing it onto the operation history.

setConcatenation

public void setConcatenation(AffineTransform transform)

Description copied from class: FXTransformPolicy

Concatenates the given AffineTransform to the initial transformation.

Overrides:

setConcatenation in class FXTransformPolicy

Parameters:

transform - The AffineTransform that is concatenated to the initial transformation.

setPreConcatenation

public void setPreConcatenation(AffineTransform transform)

Description copied from class: FXTransformPolicy

Concatenates the initial transformation to the given AffineTransform.

Overrides:

setPreConcatenation in class FXTransformPolicy

Parameters:

transform - The AffineTransform to which the initial transformation is concatenated.

setTransform

public void setTransform(AffineTransform newTransform)

Description copied from class: FXTransformPolicy

Changes the host's transformation to the given AffineTransform.

Overrides:

setTransform in class FXTransformPolicy

Parameters:

newTransform - The new AffineTransform for the host.
