  edu.umd.cs.piccolo.PNode
      edu.umd.cs.piccolo.PLayer

All Implemented Interfaces:

Printable, Serializable, Cloneable

public class PLayer
extends PNode

PLayer is a node that can be viewed directly by multiple camera nodes. Generally child nodes are added to a layer to give the viewing cameras something to look at.

A single layer node may be viewed through multiple cameras with each camera using its own view transform. This means that any node (since layers can have children) may be visible through multiple cameras at the same time.

Field Detail

PROPERTY_CAMERAS

public static final String PROPERTY_CAMERAS

The property name that identifies a change in the set of this layer's cameras (see getCamera, getCameraCount, getCamerasReference). In any property change event the new value will be a reference to the list of cameras, but old value will always be null.

PROPERTY_CODE_CAMERAS

public static final int PROPERTY_CODE_CAMERAS

The property code that identifies a change in the set of this layer's cameras (see getCamera, getCameraCount, getCamerasReference). In any property change event the new value will be a reference to the list of cameras, but old value will always be null.

Constructor Detail

PLayer

public PLayer()

Creates a PLayer without any cameras attached to it.

Method Detail

getCamerasReference

public List getCamerasReference()

Get the list of cameras viewing this layer.

Returns:

direct reference to registered cameras

getCameraCount

public int getCameraCount()

Get the number of cameras viewing this layer.

Returns:

the number of cameras attached to this layer

getCamera

public PCamera getCamera(int index)

Parameters:

index - index of camera to fetch

Returns:

camera at the given index

addCamera

public void addCamera(PCamera camera)

Add a camera to this layer's camera list. This method it called automatically when a layer is added to a camera.

Parameters:

camera - the camera to add to this layer

addCamera

public void addCamera(int index,
                      PCamera camera)

Parameters:

index - index at which the camera should be inserted

camera - Camera to add to layer

removeCamera

public PCamera removeCamera(PCamera camera)

Remove the camera from this layer's camera list.

Parameters:

camera - the camera to remove from the layer, does nothing if not found

Returns:

camera that was passed in

removeCamera

public PCamera removeCamera(int index)

Remove the camera at the given index from this layer's camera list.

Parameters:
