Constructor Detail

ASMifier

public ASMifier()

Constructs a new ASMifier. Subclasses must not use this constructor. Instead, they must use the ASMifier(int, String, int) version.

Throws:

java.lang.IllegalStateException - If a subclass calls this constructor.

ASMifier

protected ASMifier(int api,
                   java.lang.String name,
                   int id)

Constructs a new ASMifier.

Parameters:

api - the ASM API version implemented by this class. Must be one of Opcodes.ASM4 or Opcodes.ASM5.

name - the name of the visitor variable in the produced code.

id - identifier of the annotation visitor variable in the produced code.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Prints the ASM source code to generate the given class to the standard output.

Usage: ASMifier [-debug] <binary class name or class file name>

Parameters:

args - the command line arguments.

Throws:

java.lang.Exception - if the class cannot be found, or if an IO exception occurs.
