JumpInsnNode

public JumpInsnNode(int opcode,
                    Label label)

Constructs a new JumpInsnNode object.

Parameters:

opcode - the opcode of the type instruction to be constructed. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.

label - the operand of the instruction to be constructed. This operand is a label that designates the instruction to which the jump instruction may jump.

Method Detail

setOpcode

public void setOpcode(int opcode)
