soot.toDex.instructions

Class Insn21t

java.lang.Object

soot.toDex.instructions.AbstractInsn

soot.toDex.instructions.InsnWithOffset

soot.toDex.instructions.Insn21t

All Implemented Interfaces:

java.lang.Cloneable, Insn, OneRegInsn

public class Insn21t
extends InsnWithOffset
implements OneRegInsn

The "21t" instruction format: It needs two 16-bit code units, has one register and is used for jump targets (hence the "t").

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