Examples of org.olap4j.mdx.ParseTreeNode

org.olap4j.mdx.ParseTreeNode
Node in a parse tree representing a parsed MDX statement.
To convert a parse tree to an MDX string, use a {@link ParseTreeWriter}and the {@link #unparse(ParseTreeWriter)} method. @author jhyde @version $Id: ParseTreeNode.java 315 2010-05-29 00:56:11Z jhyde $ @since Jun 4, 2007
