Note About MVEL Documentation

This is the documentation for MVEL 1.2.x and 1.3.x. If you are using MVEL 2.0, please proceed to the Language Guide for 2.0

MVEL has largely been inspired by Java syntax, but has some fundamental differences aimed at making it more efficient as an expression language, such as operators that directly support collection, array and string matching, as well as regular expressions.

In addition to the expression language, MVEL serves as a templating language for configuration and string construction.

MVEL 1.x expressions may consist of:

  • Property expressions
  • Boolean expressions
  • Method invocations
  • Variable assignments
