java.lang.Object
cloud.opencode.base.classloader.OpenMetadata
public final class OpenMetadata extends Object
OpenMetadata - Metadata Reading Facade OpenMetadata - 元数据读取门面

Unified entry point for class metadata reading without loading classes.

不加载类读取类元数据的统一入口。

Features | 主要功能:

  • Read class metadata by name - 按名称读取类元数据
  • Read class metadata from Class - 从 Class 读取类元数据
  • Read class metadata from resource - 从资源读取类元数据
  • Batch reading from package - 从包批量读取

Usage Examples | 使用示例:

// Read by class name
ClassMetadata metadata = OpenMetadata.read("com.example.MyClass");

// Read from Class object
ClassMetadata metadata = OpenMetadata.read(MyClass.class);

// Check annotations without loading
if (metadata.hasAnnotation("org.springframework.stereotype.Service")) {
    // Handle service class
}

// Batch read
List<ClassMetadata> all = OpenMetadata.readPackage("com.example");
