org.wso2.charon3.core.utils.codeutils.FilterTreeManager

public class FilterTreeManager
extends Object

This class is basically for creating a binary tree which preserves the precedence order with simple filter (eg : userName eq vindula) expressions as terminals of the tree and all the logical operators (and, or, not)as the non-terminals of the tree.

All terminals are filter expressions hence denoted by ExpressionNodes and all non terminal nodes are operators hence denoted by OperatorNodes.
