Record Class JarInfo

java.lang.Object
java.lang.Record
cloud.opencode.base.classloader.conflict.JarInfo
Record Components:
path - the absolute path to the JAR file | JAR 文件的绝对路径
version - the version from MANIFEST.MF, or null if not present | MANIFEST.MF 中的版本，不存在则为 null
name - the file name of the JAR | JAR 的文件名
public record JarInfo(Path path, String version, String name) extends Record
Immutable information about a JAR file JAR 文件的不可变信息

Captures the path, version, and name of a JAR file for use in conflict detection. Version is extracted from MANIFEST.MF (Implementation-Version or Bundle-Version); it may be null if not present.

捕获 JAR 文件的路径、版本和名称，用于冲突检测。版本从 MANIFEST.MF (Implementation-Version 或 Bundle-Version) 提取；如果不存在则为 null。

Features | 主要功能:

  • Immutable record - 不可变记录
  • Version extraction from MANIFEST.MF - 从 MANIFEST.MF 提取版本
  • Null-safe version field - 版本字段空值安全

Usage Examples | 使用示例:

JarInfo info = new JarInfo(Path.of("/libs/guava-31.jar"), "31.1-jre", "guava-31.jar");
System.out.println(info.name());    // "guava-31.jar"
System.out.println(info.version()); // "31.1-jre"

Security | 安全性:

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