2.1

Field Summary

Fields

Modifier and Type	Field	Description
static final int	COMPACT	This mode is used to compact the class name to a simple name instead of a qualified name.
static final int	DEFAULT	The mode is the default mode to disassemble IClassFileReader.
static final int	DETAILED	The mode is the detailed mode to disassemble IClassFileReader.
static final int	SYSTEM	This mode corresponds to the detailed mode plus the constant pool contents and any further information that would be useful for debugging purpose.
static final int	WORKING_COPY	This mode is used to retrive a pseudo code for working copy purpose.

Method Details

disassemble

public abstract String disassemble(byte[] classFileBytes,
 String lineSeparator)
                            throws ClassFormatException

Answers back the disassembled string of the classfile bytes using the default mode. This is an output quite similar to the javap tool, using DEFAULT mode.

Parameters:

classFileBytes - The bytes of the classfile

lineSeparator - the line separator to use.

Returns:

the disassembled string of the IClassFileReader using the default mode.

Throws:

ClassFormatException - if the classfile bytes are ill-formed

disassemble

public abstract String disassemble(byte[] classFileBytes,
 String lineSeparator,
 int mode)
                            throws ClassFormatException

Answers back the disassembled string of the classfile bytes according to the mode. This is an output quite similar to the javap tool.

Parameters:

classFileBytes - The bytes of the classfile

lineSeparator - the line separator to use.

mode - the mode used to disassemble the IClassFileReader

Returns:

the disassembled string of the IClassFileReader according to the mode

Throws:

ClassFormatException - if the classfile bytes are ill-formed

getDescription

public abstract String getDescription()

Answers a readable short description of this disassembler

Returns:

String - a string description of the disassembler
