Interface ParseTreeNode

    • Method Detail

      • accept

        <T> T accept​(ParseTreeVisitor<T> visitor)
        Accepts a visitor to this MDX parse tree node.

        The implementation should generally dispatches to the ParseTreeVisitor.visit(org.olap4j.mdx.SelectNode) method appropriate to the type of expression.

        Parameters:
        visitor - Visitor
        Returns:
        T, the specific return type of the visitor
      • getType

        Type getType()
        Returns the type of this expression.

        Returns null if this node is not an expression, for instance a SELECT node.

        Returns:
        type of this expression
      • unparse

        void unparse​(ParseTreeWriter writer)
        Converts this node into MDX text.
        Parameters:
        writer - Parse tree writer
      • getRegion

        ParseRegion getRegion()
        Returns the region of the source code which this node was created from, if it was created by parsing.

        A non-leaf node's region will encompass the regions of all of its children. For example, a the region of a function call node Crossjoin([Gender], {[Store].[USA]}) stretches from the first character of the function name to the closing parenthesis.

        Region may be null, if the node was created programmatically, not from a piece of source code.

        Returns:
        Region of the source code this node was created from, if it was created by parsing
      • deepCopy

        ParseTreeNode deepCopy()
        Creates a deep copy of this ParseTreeNode object.

        Note: implementing classes can return the concrete type instead of ParseTreeNode (using Java 1.5 covariant return types)

        Returns:
        The deep copy of this ParseTreeNode
