JEL (Java Expressions Library) is a library for evaluating simple single-line expressions in Java. The key feature of JEL is the fact that it is a compiler. The language of JEL expressions resembles the Java Language expressions as close as possible. JEL supports all Java primitive types and classes (even in the form of constants), allows one to call both static and virtual methods of Java classes (with no additinal runtime costs and no wrappers), and performs evaluation of constant subexpressions at a compile time.
