LineNumberNode

public LineNumberNode(int line,
                      LabelNode start)

Constructs a new LineNumberNode.

参数：

line - a line number. This number refers to the source file from which the class was compiled.

start - the first instruction corresponding to this line number.

方法详细信息

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.
