      extended by com.bea.p13n.content.RulesContentQuery

public class RulesContentQuery
extends ContentQueryBase

A utility class to construct a content query string expression from a ContentQueryNode from the rules engine.

This will no longer always fill-out an expression with user/request/session properties. If a PropertyProvider instance is passed into the constructor, the resulting expression will always contain only literal values; otherwise, the resulting expression will contain property references as needed and ExpressionHelper.realize() can be used.
