Class PropertyDescriptor

java.lang.Object
cloud.opencode.base.core.bean.PropertyDescriptor
public final class PropertyDescriptor extends Object
Bean Property Descriptor - Describes a single bean property Bean 属性描述符 - 描述单个 Bean 属性

Encapsulates property metadata including name, type, getter, setter, and field.

封装属性元数据，包括名称、类型、Getter、Setter 和字段。

Features | 主要功能:

  • Property metadata (name, type, readable, writable) - 属性元数据
  • Value get/set operations - 值读写操作
  • Generic type information - 泛型类型信息
  • Annotation access (from method/field) - 注解访问

Usage Examples | 使用示例:

// Get property descriptor - 获取属性描述符
PropertyDescriptor pd = OpenBean.getPropertyDescriptor(User.class, "name").orElse(null);

// Check readable/writable - 检查可读/可写
boolean readable = pd.isReadable();
boolean writable = pd.isWritable();

// Get/Set value - 读写值
Object value = pd.getValue(user);
pd.setValue(user, newValue);

Security | 安全性:

  • Thread-safe: Yes (immutable) - 线程安全: 是 (不可变)
  • Null-safe: Partial (throws on null bean) - 空值安全: 部分
