Package org.codehaus.janino Description

The classes in this package pose the core of the Janino Java^TM compiler.

The package comprises a scanner (Scanner, a parser (Parser) and a class file library. The parser builds a syntax tree from the "Java.*" classes that represents the parsed code. The UnitCompiler.compileUnit(boolean, boolean, boolean) method compiles this syntax tree into a ClassFile object, which can write Java^TM bytecode to an "OutputStream".
