Detailed Description

Instruction subclasses are used to represent parsed bytecode; each bytecode operation has a corresponding subclass of Instruction.

Each subclass is derived from one of

Member Function Documentation

int Instruction_byte::compile byte   bc[],
int   index
[inline, virtual]
 

Writes out the sequence of bytecodes represented by this instruction, including any arguments.

Parameters:
bc   complete array of bytecode.
index   offset of remaining bytecode at which to start writing.
Returns:
offset of the next available bytecode.

int Instruction_byte::nextOffset int   curr [inline]
 

Returns the next available offset assuming this instruction begins on the indicated offset; default assumes no arguments.

Parameters:
curr   offset this instruction would be on.
Returns:
next available offset.

int Instruction_byte::parse byte   bc[],
int   index
[inline, virtual]
 

Assuming the actual bytecode for this instruction has been extracted already, and index is the offset of the next byte, this method parses whatever arguments the instruction requires and return the offset of the next available byte.

Parameters:
bc   complete array of bytecode.
index   offset of remaining bytecode after this instruction's bytecode was parsed.
Returns:
offset of the next available bytecode.

String Instruction_byte::toString cp_info   constant_pool[] [inline]
 

For displaying instructions.

Parameters:
constant_pool   constant pool of associated ClassFile
Returns:
String representation of this instruction.
