Interface TreeWalker

Deprecated. This class comes from the old Java 1.2 UIX codebase and should not be used anymore.

@Deprecated
public interface TreeWalker

Callback API for walking the UINode tree. TreeWalkers can be used (with TreeWalkerUtils) to traverse the tree with proper support for composite rendering.

Method Summary

boolean	walkChildren(UIXRenderingContext context, UINode node, java.lang.Object value, Path path) Deprecated. Callback method that will be called once for every node to determine if the children of that node should be walked to.
java.lang.Object	walkNode(UIXRenderingContext context, UINode node, java.lang.Object previousValue, Path path) Deprecated. Callback method that will be called once for every node the tree walker walks.

Method Detail

walkNode

java.lang.Object walkNode(UIXRenderingContext context,
                          UINode node,
                          java.lang.Object previousValue,
                          Path path)
                          throws java.io.IOException

Deprecated.

Callback method that will be called once for every node the tree walker walks.

Parameters:

context - the rendering context for this node

node - the current UINode

previousValue - the last value returned from walkNode, or null on the first node walked

path - a Path object from the node where walking started

Returns:

a new value. Frequently, this will be previousValue.

Throws:

java.io.IOException - if this method writes output

walkChildren

boolean walkChildren(UIXRenderingContext context,
                     UINode node,
                     java.lang.Object value,
                     Path path)

Deprecated.

Callback method that will be called once for every node to determine if the children of that node should be walked to.

Parameters:

context - the rendering context for this node

node - the current UINode

value - the last value returned from walkNode

path - a Path object from the node where walking started

Returns:

if true, walking continues to the children of this node. If false, the siblings of this ndoe will still be walked to.
