Field Detail

name

protected final String name

The name of the visitor variable in the produced code.

id

protected final int id

Identifier of the annotation visitor variable in the produced code.

labelNames

protected Map<Label,String> labelNames

The label names. This map associates String values to Label keys. It is used only in ASMifierMethodVisitor.

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:: IllegalStateException - If a subclass calls this constructor.

ASMifier

protected ASMifier(int api,
                   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(String[] args)
                 throws 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:: Exception - if the class cannot be found, or if an IO exception occurs.
