Field Detail

listenerList

protected java.util.ArrayList listenerList

List to contain interested listeners.

Constructor Detail

BaseTextureNode

protected BaseTextureNode(java.lang.String name)

Construct a new base representation of a texture node/

Parameters:

name - The name of the type of node

Method Detail

getCacheString

public java.lang.String getCacheString(int stage)

Get a string for cacheing this object. Default implementation returns null.

Specified by:

getCacheString in interface VRMLTextureNodeType

Parameters:

stage - The stage number, 0 for all single stage textures

Returns:

A string to use in lookups. Typically the url loaded.

addTextureListener

public void addTextureListener(VRMLTextureListener l)

Add a listener for texture changes. If the listener is already registered then this request is ignored.

Specified by:

addTextureListener in interface VRMLTextureNodeType

Parameters:

l - The listener instance to be added

removeTextureListener

public void removeTextureListener(VRMLTextureListener l)

Removes a listener for texture changes. If the listener is not already registered, the request is ignored.

Specified by:

removeTextureListener in interface VRMLTextureNodeType

Parameters:

l - The listener to be removed

fireTextureImageChanged

protected void fireTextureImageChanged(int idx,
                                       VRMLNodeType node,
                                       NIOBufferImage image,
                                       java.lang.String url)

Fire a textureImageChanged event to the listeners.

Parameters:

idx - The stage

node - The node which changed

image - The new image

url - The url used to load or null.

fireTextureParamsChanged

protected void fireTextureParamsChanged(int len,
                                        VRMLNodeType node,
                                        int[] mode,
                                        int[] source,
                                        int[] function,
                                        float alpha,
                                        float[] color)

Fire a textureParamsChanged event to the listeners.

Parameters:

len - The number of stages

node - The node which changed

mode - The list of modes
