包路径：org.objectweb.asm.tree.LocalVariableNode
类名称：LocalVariableNode

LocalVariableNode介绍

[英]A node that represents a local variable declaration.
[中]表示局部变量声明的节点。

代码示例

代码示例来源：origin: jphp-group/jphp

@SuppressWarnings("unchecked")
void writeFooter(){
  LabelNode endL = new LabelNode();
  node.instructions.add(endL);
  for(LocalVariable variable : localVariables.values()){
    String description = Type.getDescriptor(variable.getClazz() == null ? Object.class : variable.getClazz());
    if (variable.name.equals("~this")) {
      //if (variable.getClazz() != Memory.class && !clazz.statement.isTrait()) {
        description = "L" + clazz.entity.getCompiledInternalName() + ";";
      //}
    }
    node.localVariables.add(new LocalVariableNode(
        variable.name,
        description,
        null,
        variable.label == null ? labelStart : variable.label,
        variable.getEndLabel() == null ? endL : variable.getEndLabel(),
        variable.index
    ));
  }
  //node.maxStack = this.stackMaxSize;  !!! we don't need this, see: ClassWriter.COMPUTE_FRAMES
  //node.maxLocals = this.localVariables.size();
}
