Constructor Summary

PathTreeFormatterDefault()

Method Summary

void	onBacktrack(PrintWriter pwriter, int depth) This method is called after we have traversed the children and before we start to traverse the siblings of the current node.
void	onEndOfNode(PrintWriter pwriter, int depth) This method is called after we have traversed all of the children and siblings of the node.
void	onFinish(PrintWriter pwriter) This method is called after all traversing is done.
void	onLeaf(PrintWriter pwriter, Object data, int depth) This method is called when we reach a leaf node.
void	onNode(PrintWriter pwriter, Object data, int depth) This method is called just before we start traversing the children.
void	onStart(PrintWriter pwriter) This method is called before any traversing is done.
void	onStartOfNode(PrintWriter pwriter, int depth) This method is called when we first traverse to a new node.

onStartOfNode

public void onStartOfNode(PrintWriter pwriter,
                          int depth)

This method is called when we first traverse to a new node.

Specified by:

onStartOfNode in interface PathTreeFormatter

Parameters:

pwriter - is the PrintWriter to print out to.

depth - is the current depth we are at relative to the root.

onEndOfNode

public void onEndOfNode(PrintWriter pwriter,
                        int depth)

This method is called after we have traversed all of the children and siblings of the node.

Specified by:

onEndOfNode in interface PathTreeFormatter

Parameters:

pwriter - is the PrintWriter to print out to.

depth - is the current depth we are at relative to the root.

onBacktrack

public void onBacktrack(PrintWriter pwriter,
                        int depth)

Specified by:

onBacktrack in interface PathTreeFormatter

Parameters:

pwriter - is the PrintWriter to print out to.

depth - is the current depth we are at relative to the root.

onLeaf

public void onLeaf(PrintWriter pwriter,
                   Object data,

Specified by:

onLeaf in interface PathTreeFormatter

Parameters:

pwriter - is the PrintWriter to print out to.

depth - is the current depth we are at relative to the root.

onNode

public void onNode(PrintWriter pwriter,
                   Object data,
                   int depth)

Specified by:

onNode in interface PathTreeFormatter

Parameters:

pwriter - is the PrintWriter to print out to.

depth - is the current depth we are at relative to the root.

onFinish

public void onFinish(PrintWriter pwriter)
