Method Detail

dispatch

public T dispatch(AttributeNode n)

Processes a AttributeNode. This invokes pre(Node), if that returns null then process(AttributeNode) is invoked, and it that returns null then process(SingleContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(ChoiceNode n)

Processes a ChoiceNode. This invokes pre(Node), if that returns null then process(ChoiceNode) is invoked, and it that returns null then process(MultiContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(ElementNode n)

Processes a ElementNode. This invokes pre(Node), if that returns null then process(ElementNode) is invoked, and it that returns null then process(SingleContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(InterleaveNode n)

Processes a InterleaveNode. This invokes pre(Node), if that returns null then process(InterleaveNode) is invoked, and it that returns null then process(MultiContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(OneOrMoreNode n)

Processes a OneOrMoreNode. This invokes pre(Node), if that returns null then process(OneOrMoreNode) is invoked, and it that returns null then process(SingleContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(SequenceNode n)

Processes a SequenceNode. This invokes pre(Node), if that returns null then process(SequenceNode) is invoked, and it that returns null then process(MultiContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

dispatch

public T dispatch(TextNode n)

Processes a TextNode. This invokes pre(Node), if that returns null then process(TextNode) is invoked, and if that returns null then process(NoContentNode) is invoked. Finally, post(Node, Object) is invoked.

Parameters:

n - node

Returns:

result

post

public void post(Node n,
