本文整理了Java中org.objectweb.asm.tree.TypeInsnNode类的一些代码示例，展示了TypeInsnNode类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TypeInsnNode类的具体详情如下：
包路径：org.objectweb.asm.tree.TypeInsnNode
类名称：TypeInsnNode

TypeInsnNode介绍

[英]A node that represents a type instruction. A type instruction is an instruction that takes a type descriptor as parameter.
[中]表示类型指令的节点。类型指令是以类型描述符为参数的指令。
