Constructor Detail

Textifier

public Textifier()

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

Throws:: IllegalStateException - If a subclass calls this constructor.

Textifier

protected Textifier(int api)

Constructs a new Textifier.

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

Method Detail

main

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

Prints a disassembled view of the given class to the standard output.

Usage: Textifier [-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.
