Package com.acsinet_solutions.util.expr Description

Generic expression utilities; this package defines interfaces and basic implementations regarding expression needs on utility classes and in the framework as a whole. A complete expression evaluation facility is not provided here though. Expression evaluation is performed in some parts of the framework by dedicated libraries like JEXL, Velocity or XPath libraries like JXPath. The interfaces and classes provided here are meant only as facades, or complementary features that are needed in some cases.
