Package org.eclipse.gef.fx.anchors

Class OrthogonalProjectionStrategy

java.lang.Object

org.eclipse.gef.fx.anchors.ProjectionStrategy

org.eclipse.gef.fx.anchors.OrthogonalProjectionStrategy

All Implemented Interfaces:

IComputationStrategy

public class OrthogonalProjectionStrategy
extends ProjectionStrategy

An IComputationStrategy that computes anchor position by orthogonally projecting the respective anchored reference point to the outline of the anchorage reference geometry so that the respective point has minimal distance to the anchored reference point and resembles the same x- (vertical projection) or y-coordinate (horizontal projection).

computeProjectionInScene

protected Point computeProjectionInScene(List<ICurve> anchorageOutlinesInScene,
 Point anchoredReferencePointInScene,
 Set<IComputationStrategy.Parameter<?>> parameters)

Description copied from class: ProjectionStrategy

Computes the anchorage reference position in scene coordinates, based on the given anchorage outlines and the given anchored reference point.

Overrides:

computeProjectionInScene in class ProjectionStrategy

Parameters:

anchorageOutlinesInScene - A list of ICurves that describe the outline of the anchorage.

anchoredReferencePointInScene - The reference Point of the anchored for which the anchorage reference Point is to be determined.

parameters - The parameters available for the computation.

Returns:

The anchorage reference position.

getRequiredParameters

public Set<Class<? extends IComputationStrategy.Parameter<?>>> getRequiredParameters()

Description copied from interface: IComputationStrategy

Returns the types of parameters required by this strategy.

Specified by:

getRequiredParameters in interface IComputationStrategy

Overrides:

getRequiredParameters in class ProjectionStrategy

Returns:

The parameters required by this strategy.
