基于服务模式规约的构件剪裁

Component tailoring based on service-pattern specification

构件剪裁是一种高效的提高构件可用性的方法,但是如何实施有效的构件剪裁一直是研究中的难点。对构件功能逻辑的准确理解有助于实施有效的构件剪裁。基于此,首先从构件提供者角度依据构件接口中方法间的关联性分析,给出了服务模式的概念和构件的服务模式规约。接着基于构件的服务模式规约,提供了一种便于使用者验证构件剪裁有效性的算法。最后结合详细的示例分析了算法的可行性。

Component tailoring has been an efficient approach to improve component usability, but how to implement it is still an open issue. Deep and accurate appreciation of component function logic can help user to carry out valid component tailoring. So, first, concept of service pattern and its specification are given based on analysis of function-to-function relation from the component provider＇s view. Then based on the given service-pattern specification, an algorithm is proposed to verify the validity of component tailoring im- plemented by user, Finally, an example is given to show the feasibility of algorithm.
