Class ContentQuery

public class ContentQuery

extends ContentQueryBase

A utility class to construct a content query string expression from a <contentQuery> XML Element.

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