      • simplify

        public Expr simplify()
        Description copied from interface: Expr
        Simplifies the XPath expression. For example, the expression //para[1 = 1] could be simplified to //para. In practice, this is usually a noop. Jaxen does not currently perform any simplification.

        simplify in interface Expr
        Overrides:
        simplify in class DefaultExpr
        Returns:

                                  throws JaxenException
        Description copied from interface: Expr

The result will be a java.lang.Double for expressions that return a number, a java.lang.String for expressions that return a string, a java.lang.Boolean for expressions that return a boolean, and a java.util.List for expressions that return a node-set. In the latter case, the elements of the list are the actual objects from the source document model. Copies are not made.
        Specified by:
        evaluate in interface Expr
        Parameters:
        context - the context in which the expression is evaluated
        Returns:
        an object representing the result of the evaluation
