Java Expression Evaluator

Features

• supports multiple evaluation contexts
• easy to use: you only submit a code string and you get the result
• easly define new functions and load them with properties files
• user-defined functions {%functionXYZ {param1}, {param2}, ...}
• variables per context: {:var1}
• system variables: {@sysvar1}
• dynamic function or variable resolving: {>{':'}{:myvarname}}
• expressions: {= ({2} + {4}) * ({1.5}-{5}) }
• validation: {%mathRandom} < {10} * ({:z1} + {:z2} + {1})
• type safety and type casting: {(N)'3.5'} casts string 3.5 to number
• boolean operators: and, or, !=, =, > ,<, >=, <=
