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

• Instruction
• Instruction_noargs (an Instruction with no embedded arguments)
• Instruction_byte (an Instruction with a single byte data argument)
• Instruction_bytevar (a byte argument specifying a local variable)
• Instruction_byteindex (a byte argument specifying a constant pool index)
• Instruction_int (an Instruction with a single short data argument)
• Instruction_intvar (a short argument specifying a local variable)
• Instruction_intindex (a short argument specifying a constant pool index)
• Instruction_intbranch (a short argument specifying a code offset)
• Instruction_longbranch (an int argument specifying a code offset)

Member Function Documentation

int Instruction_Iinc::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. See also: ClassFile::unparseMethod , Instruction::parse Reimplemented from Instruction_bytevar. Definition at line 144 of file Instruction_Iinc.java.

int Instruction_Iinc::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. See also: ClassFile::relabel Reimplemented from Instruction_bytevar. Definition at line 149 of file Instruction_Iinc.java.

int Instruction_Iinc::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. See also: ByteCode::disassemble_bytecode , Instruction::compile Reimplemented from Instruction_bytevar. Definition at line 150 of file Instruction_Iinc.java.

String Instruction_Iinc::toString (  cp_info   constant_pool[] )  [inline]

For displaying instructions. Parameters: constant_pool   constant pool of associated ClassFile Returns: String representation of this instruction. Reimplemented from Instruction_bytevar. Definition at line 168 of file Instruction_Iinc.java.
