public Iinc(int slot,
            int increment)

Method Detail

stackDiff

public int stackDiff()

Description copied from class: Bytecode

This method determines the change in stack resulting from this bytecode. For example, +1 indicates the instruction puts one thing onto the stack. Likewise, -2 means this instruction takes two things off the stack. The primary purpose of this method is to help compute the maxStack requirement for a method.

Specified by:

stackDiff in class Bytecode

Returns:

toString

public String toString()

Overrides:

toString in class Object

toBytes

public byte[] toBytes(int offset,
                      Map<String,Integer> labelOffsets,
                      Map<Constant.Info,Integer> constantPool)

Description copied from class: Bytecode

Translate this Java bytecode into bytes. If the bytecode requires a constant pool item which is not present in the constantPool map, then the appropriate CONSTANT_Info object is added, and given the next available index.

Specified by:

toBytes in class Bytecode

Parameters:

offset - Offset of this bytecode

labelOffsets - Offsets of any labels used in branch bytecodes

constantPool - Indices of constant pool items used in various bytecodes (e.g. ldc, putfield, etc)

Returns:

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
