soot.toDex.instructions

Class Insn22t

java.lang.Object

soot.toDex.instructions.AbstractInsn

soot.toDex.instructions.InsnWithOffset

soot.toDex.instructions.Insn22t

All Implemented Interfaces:

Cloneable, Insn, OneRegInsn, TwoRegInsn

public class Insn22t
extends InsnWithOffset
implements TwoRegInsn

The "22t" instruction format: It needs two 16-bit code units, has two registers and is used for jump targets (hence the "t").

It is used e.g. by the opcode "if-eq" for conditional jumps to a 16-bit wide offset.
