Class ProxyShapeNodeRealizer

java.lang.Object
  y.view.NodeRealizer
      y.view.ShapeNodeRealizer
          y.view.ProxyShapeNodeRealizer

All Implemented Interfaces:

NodeLayout

Direct Known Subclasses:

ProxyAutoBoundsNodeRealizer

public class ProxyShapeNodeRealizer
extends ShapeNodeRealizer

A ShapeNodeRealizer that can act as a proxy to another internally used realizer. Also, this class can maintain a list of realizers, that will be copied, saved, and restored when performing these operations on this class. Usually, the held realizers define the set of possible delegation targets of this class.

Almost all inherited methods of this class are overwritten to delegate to the currently set realizer delegate. E.g. the implementation of setSelected is basically

if (rd != null) rd.setSelected(s); else super.setSelected(s);

with rd being the current realizer delegate. Notable exceptions to this rule are read(java.io.ObjectInputStream), write(java.io.ObjectOutputStream), and createCopy(NodeRealizer).

Description copied from class: ShapeNodeRealizer

Special Intersection handling for some types of shape. When shape is an ellipse or an rectangle, the intersection point is calculated, not iteratively determined.

Overrides:

findIntersection in class ShapeNodeRealizer

Parameters:

ix - the x-coordinate of a point inside the realizer's visual bounds.

iy - the y-coordinate of a point inside the realizer's visual bounds.

ox - the x-coordinate of a point outside the realizer's visual bounds.

oy - the y-coordinate of a point outside the realizer's visual bounds.

result - output parameter for the absolute world coordinates of the calculated intersection point.

Returns:

true if (ix,iy) lies inside and (ox,oy) lies outside this realizer's visual bounds; false otherwise.

getPortCandidates

public YList getPortCandidates(double gridResolution)

Description copied from class: NodeRealizer

Returns a list of YPoints that contains absolute(!) coordinates of port candidate locations that are suitable for the given grid resolution.

Overrides:

getPortCandidates in class NodeRealizer

Parameters:

gridResolution - the distance between two grid points, the origin of the grid is at (0,0) in world coordinates

Returns:

a YList of YPoint instances, each specifying an absolute port position

getMouseInputEditorProvider

public MouseInputEditorProvider getMouseInputEditorProvider()

Returns a provider, that can be used to query for a mouse input editor for this realizer. This implementation delegates this call to its current realizer delegate, if there is one. Otherwise null is returned.

Overrides:

getMouseInputEditorProvider in class NodeRealizer

Returns:

an implementation of interface MouseInputEditorProvider or null, if no such provider is bound to this realizer.

paintNode

protected void paintNode(java.awt.Graphics2D gfx)

Description copied from class: ShapeNodeRealizer

Paints the node. Internally, painting is performed by calling the following protected methods in the given order:

1. ShapeNodeRealizer.paintHotSpots(Graphics2D) (only when selected)
2. ShapeNodeRealizer.paintShadow(Graphics2D)
3. ShapeNodeRealizer.paintFilledShape(Graphics2D)
4. NodeRealizer.paintPorts(Graphics2D)
5. NodeRealizer.paintText(Graphics2D)
6. ShapeNodeRealizer.paintShapeBorder(Graphics2D)

If raised border painting is disabled, ShapeNodeRealizer.paintShapeBorder(Graphics2D) is called before NodeRealizer.paintPorts(Graphics2D) instead of after NodeRealizer.paintText(Graphics2D).

Overrides:

paintNode in class ShapeNodeRealizer

paintHotSpots
