Examples of CompiledExpression

org.apache.commons.jxpath.CompiledExpression
Represents a compiled XPath. The interpretation of compiled XPaths may be faster, because it bypasses the compilation step. The reference implementation of JXPathContext also globally caches some of the results of compilation, so the direct use of JXPathContext is not always less efficient than the use of CompiledExpression.
Use CompiledExpression only when there is a need to evaluate the same expression multiple times and the CompiledExpression can be conveniently cached.
To acqure a CompiledExpression, call {@link JXPathContext#compile JXPathContext.compile} @author Dmitri Plotnikov @version $Revision: 1.4 $ $Date: 2003/03/11 00:59:11 $
