Record Class CachedScanResult

java.lang.Object
java.lang.Record
cloud.opencode.base.classloader.scanner.CachedScanResult
public record CachedScanResult(String classpathHash, Set<String> classNames, String timestamp) extends Record
Cached Scan Result - Immutable record representing a cached class scan result 缓存扫描结果 - 表示缓存的类扫描结果的不可变记录

Stores the scan result along with a classpath hash for cache validation. If the classpath hash changes between runs, the cache is considered stale.

存储扫描结果及类路径哈希用于缓存验证。 如果类路径哈希在两次运行之间发生变化，则缓存视为过期。

Features | 主要功能:

  • Immutable record with defensive copy - 防御性拷贝的不可变记录
  • JSON serialization/deserialization - JSON 序列化/反序列化
  • Classpath hash validation - 类路径哈希验证

Usage Examples | 使用示例:

CachedScanResult result = new CachedScanResult(hash, classNames, timestamp);
String json = result.toJson();
CachedScanResult restored = CachedScanResult.fromJson(json);

Security | 安全性:

  • Thread-safe: Yes (immutable) - 线程安全: 是 (不可变)
  • Null-safe: Yes - 空值安全: 是
Since:
JDK 25, opencode-base-classloader V1.0.3

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
