Javassist (Java programming assistant) is a load-time
reflective system for Java. It is a class library for
editing bytecodes in Java; it enables Java programs to
define a new class at runtime and to modify a class file
before the JVM loads it. Unlike other similar systems,
Javassist provides source-level abstraction; programmers
can modify a class file without detailed knowledge of the
Java bytecode. They do not have to even write an inserted
bytecode sequence; Javassist instead can compile a fragment
of source text on line (for example, just a single
statement). This ease of use is a unique feature of
Javassit against other tools.
