label

public LabelNode label

The operand of this instruction. This operand is a label that designates the instruction to which this instruction may jump.

构造方法详细信息

JumpInsnNode

public JumpInsnNode(int opcode,
                    LabelNode label)

Constructs a new JumpInsnNode.

参数：

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.

方法详细信息

setOpcode

public void setOpcode(int opcode)

Sets the opcode of this instruction.

参数：

opcode - the new instruction opcode. 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.

getType

public int getType()

从类 AbstractInsnNode 复制的描述

Returns the type of this instruction.

指定者：

类 AbstractInsnNode 中的 getType

返回：

the type of this instruction, i.e. one the constants defined in this class.

accept

public void accept(MethodVisitor mv)

从类 AbstractInsnNode 复制的描述

Makes the given code visitor visit this instruction.

指定者：

类 AbstractInsnNode 中的 accept

参数：

mv - a code visitor.

clone

public AbstractInsnNode clone(Map labels)

从类 AbstractInsnNode 复制的描述

Returns a copy of this instruction.

指定者：

类 AbstractInsnNode 中的 clone

参数：

labels - a map from LabelNodes to cloned LabelNodes.

返回：

a copy of this instruction. The returned instruction does not belong to any InsnList.
