Class CommandLineConfigSource

java.lang.Object
cloud.opencode.base.config.source.CommandLineConfigSource
All Implemented Interfaces:
ConfigSource
public class CommandLineConfigSource extends Object implements ConfigSource
Command Line Arguments Configuration Source 命令行参数配置源

Parses command line arguments into configuration properties with support for multiple formats: --key=value, -Dkey=value, and boolean flags.

将命令行参数解析为配置属性,支持多种格式: --key=value, -Dkey=value 和布尔标志。

Features | 主要功能:

  • Multiple argument formats - 多种参数格式
  • Boolean flag support (--flag -> flag=true) - 布尔标志支持
  • Highest priority (200) - 最高优先级(200)
  • Order preservation - 顺序保留

Usage Examples | 使用示例:

// Parse arguments
String[] args = {
    "--server.port=9090",
    "-Dapp.env=prod",
    "--debug",
    "--database.url=jdbc:mysql://localhost/db"
};

ConfigSource source = new CommandLineConfigSource(args);
// server.port=9090
// app.env=prod
// debug=true
// database.url=jdbc:mysql://localhost/db

Supported Formats | 支持的格式:

--key=value     -> key=value
-Dkey=value     -> key=value
--flag          -> flag=true
-Dflag          -> flag=true

Performance | 性能特性:

  • Time complexity: O(n) for parsing - 时间复杂度: 解析为O(n)
  • Arguments parsed once at creation - 参数在创建时解析一次

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
  • Immutable properties - 不可变属性
