JEL (Java Expressions Library) is a library for evaluating a simple single line expressions in Java. The key feature of JEL is the fact that it is a compiler. It supports full set of Java operators and primitive types, allows to call both static and virtual methods of Java classes (with no additional runtime costs and no wrappers), and performs evaluation of constant subexpressions at a compile time.
