Class LambdaInfo

java.lang.Object
cloud.opencode.base.reflect.lambda.LambdaInfo
public class LambdaInfo extends Object
Lambda Information Holder Lambda信息持有者

Holds metadata extracted from a serialized lambda expression.

持有从序列化lambda表达式提取的元数据。

Features | 主要功能:

  • Lambda implementation class discovery - Lambda实现类发现
  • Implementation method access - 实现方法访问
  • SerializedLambda metadata extraction - SerializedLambda元数据提取

Usage Examples | 使用示例:

LambdaInfo info = LambdaInfo.from((SerializableFunction<User, String>) User::getName);
String methodName = info.getImplMethodName();
Class<?> implClass = info.getImplClass();

Security | 安全性:

  • Thread-safe: Yes (immutable after construction) - 线程安全: 是（构造后不可变）
  • Null-safe: No (lambda must be non-null and serializable) - 空值安全: 否（lambda须非空且可序列化）
Since:
JDK 25, opencode-base-reflect V1.0.0
