org.eclipse.gef.fx.anchors.AbstractAnchor

org.eclipse.gef.fx.anchors.StaticAnchor

All Implemented Interfaces:

IAnchor

Direct Known Subclasses:

AbstractRouter.VolatileStaticAnchor

public class StaticAnchor
extends AbstractAnchor

An StaticAnchor provides a position for each AnchorKey, based on a reference position relative to the anchorage Node, to which the StaticAnchor is bound, or based on a (global) static reference position in case the StaticAnchor is unbound.

Constructor Details

StaticAnchor

public StaticAnchor(Node anchorage,
 Point referencePositionInAnchorageLocal)

Creates an StaticAnchor that is bound to the provided anchorage. It will used the passed in reference position (in the local coordinate system of the anchorage Node) to compute positions (see AbstractAnchor.positionsUnmodifiableProperty()) for all attached AnchorKeys (in the local coordinate system of the attached AnchorKey's Node ).

In case the anchorage Node or any of its ancestors are changed in a way that will affect the position, the AbstractAnchor.positionsUnmodifiableProperty() will be updated.

Parameters:

anchorage - The anchorage Node to bind this StaticAnchor to.

referencePositionInAnchorageLocal - The position within the local coordinate space of the anchorage Node, which is used to compute the position (in scene coordinates) for all attached AnchorKeys.

StaticAnchor

public StaticAnchor(Point referencePositionInScene)

Creates an StaticAnchor that is not bound to an anchorage Node and will always provide the passed in position (in scene coordinates) for all attached AnchorKeys (i.e. anchored Nodes).

Parameters:

referencePositionInScene - The position in scene coordinates to be provided for all attached AnchorKeys.

Method Details

computePosition

protected Point computePosition(AnchorKey key)

Description copied from class: AbstractAnchor

Recomputes the position for the given attached AnchorKey by delegating to the respective IComputationStrategy.

Specified by:

computePosition in class AbstractAnchor

Parameters:

key - The AnchorKey for which to compute an anchor position.

Returns:

The point for the given AnchorKey in local coordinates of the anchored Node.

getReferencePosition

public Point getReferencePosition()

Returns the reference position of this StaticAnchor.

Returns:

The reference position of this StaticAnchor.

referencePositionProperty

public ObjectProperty<Point> referencePositionProperty()

Returns the ObjectProperty that manages the reference position of this StaticAnchor.

See Also:

• getReferencePosition()
• setReferencePosition(Point)

setReferencePosition

public void setReferencePosition(Point referencePosition)

Sets the reference position of this StaticAnchor to the given value.

Parameters:

referencePosition - The new reference position for this StaticAnchor.

toString

public String toString()

Overrides:

toString in class Object
