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.

方法详细资料

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()

从类复制的说明: AbstractInsnNode

Returns the type of this instruction.

指定者:

getType 在类中 AbstractInsnNode

返回:

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

accept

public void accept(MethodVisitor mv)

从类复制的说明: AbstractInsnNode

Makes the given code visitor visit this instruction.

指定者:

accept 在类中 AbstractInsnNode

参数:

mv - a code visitor.

clone

public AbstractInsnNode clone(Map labels)

从类复制的说明: AbstractInsnNode

Returns a copy of this instruction.

指定者:

clone 在类中 AbstractInsnNode

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.
