Class FilterTreeNode

java.lang.Object
  com.jcorporate.expresso.core.security.filters.FilterTreeNode

All Implemented Interfaces:

Serializable

public class FilterTreeNode

extends Object

implements Serializable

This class provides a "filter parse tree" interface to the system. It is a dual action object, it's a union of a node, and a leaf. Thus allowing us to play with TreeMap/HashMap quickly.

Please Note: This class is unsynchronized for performance reasons, please be careful when using in a multi-threaded environment outisde of the Filter class.

Throws:

Exception - if a replacement string already exists for this

setSubnode

public void setSubnode(ReusableChar key,
                       FilterTreeNode newSubnode)
                throws Exception

Parameters:

key - The character key to look up the subnode.

Throws:

Exception

subnodeExists

public boolean subnodeExists(ReusableChar key)

Returns:

true if a subnode exists for this key.

getSubnode

public FilterTreeNode getSubnode(ReusableChar key)

Parameters:

key - The key to base this subnode after.

Returns:

the subnode that exists at this key, or null if it doesn't exist

dumpNode

public void dumpNode(org.apache.log4j.Category log)

Dumps the contents of the tree to the log. (ie dumps this node and all subnodes.

dumpNode

public void dumpNode()
