022 * Creates Expression objects. 
023 * <p>
024 * To create a JEXL Expression object, pass
025 * valid JEXL syntax to the static createExpression() method:
026 * </p>
027 *
028 * <pre>
029 * String jexl = "array[1]";
030 * Expression expression = ExpressionFactory.createExpression( jexl );
031 * </pre>
032 *
033 * <p>
034 * When an {@link Expression} object is created, the JEXL syntax is
035 * parsed and verified.  If the supplied expression is neither an
036 * expression nor a reference, an exception is thrown from createException().
037 * </p>
038 * 
039 * <p>
040 * This is a convenience class; using an instance of a {@link JexlEngine}
041 * that serves the same purpose with more control is recommended.
042 * </p>
043 * @since 1.0
044 * 
045 * @version $Id$
046 * @deprecated Create a JexlEngine and use the createScript method on that instead.
