Class InMemoryConfigSource

java.lang.Object
cloud.opencode.base.config.source.InMemoryConfigSource
All Implemented Interfaces:
ConfigSource
public class InMemoryConfigSource extends Object implements ConfigSource
In-Memory Configuration Source 内存配置源

Stores configuration in memory with support for runtime updates and programmatic configuration.

在内存中存储配置,支持运行时更新和编程配置。

Features | 主要功能:

  • Programmatic configuration - 编程配置
  • Runtime updates - 运行时更新
  • Thread-safe mutations - 线程安全的修改
  • Low priority (10) - 低优先级(10)

Usage Examples | 使用示例:

// From map
Map<String, String> props = Map.of(
    "app.name", "MyApp",
    "server.port", "8080"
);
InMemoryConfigSource source = new InMemoryConfigSource(props);

// Runtime updates
source.setProperty("server.port", "9090");
source.removeProperty("old.key");

// Bulk update
source.setProperties(Map.of("key1", "val1", "key2", "val2"));

Performance | 性能特性:

  • Time complexity: O(1) for get/set - 时间复杂度: 获取/设置为O(1)
  • Thread-safe concurrent access - 线程安全的并发访问

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
  • Mutable source - 可变源
