基于Mediator模式的参数控制法

A Mediator Based Parameter Control Method

人机交互语言工具是电信网管的重要组成部分,是网管系统中使用频率最高的模块之一,命令参数的显示控制是它的实现难点.基于Mediator模式的参数控制法分离了参数表示和逻辑控制,它让每个参数专心处理自身表示,由中介者控制显示逻辑,解除了参数间的耦合关系.这种实现方法,集中了对参数的控制,减少了耦合,有利于各参数的复用,易于逻辑关系扩展,提高了命令解析效率.实际测试表明,在PIII 1.0 G CPU环境下,解析一条命令的平均时间只需0.14 s.该方法为开发网管人机交互语言工具或处理对象强耦合问题提供了一种有参考价值的实现方法.

As an important part of TMN （Telecom Management Network）, MML （Man Machine Language） tool is frequently used whose implementing difficulty is parameter＇s display controlling. Mediator based parameter controlling method separates parameter＇s visualization from logical control and each parameter concentrates on its UI, while mediator focus on logical relationships. Such implementation centralizes the logical control and decreases the coupling, whereby each parameter can be reused and the system is more extensive and effective. When working under the system with a CPU of PⅢ 1.0 GHz, it only costs 0.14 s to parse a command. This paper provides a guidance for those who develop MML tool or decouple objects interrelationship.
