Abstract
Compatibility is the precondition to ensure the correct interaction among components in composition process, how to make the mismatch components coordinate correctly is a vital problem in component composition. This paper first modeled component behavior by LTS and expressed action mapping as synchronous vector then defined the sequential relationship among synchronous vectors as adaptation contract. Thirdly we analyzed the different mismatch situations and corresponding adaptation strategies. At last designed adaptation algorithm to produce adaptor specification automatically and ensured the mismatch components can correct interaction under the mediation of adaptor and verified the validity of proposed method through an application system.
Highlights
Component based software development (CBSD) that aims at constructing new systems by compositing prefabricated reusable components have been tested can shorten the development cycle and improve software quality [1]
Components participating in the assembly be fully compatible can ensure correct interaction among components, usually components are provided by different software vendors so that the difference of operations name, operations order and operations granularity that are defined in component interfaces is almost inevitable due to different use perspectives
On the basis of forming the adaptation contract, the states of adaptation contract can be regarded as nodes, the transition under the effect of synchronous vector can be seen as edges, and the adaptation contract can be treated as a directed acyclic graph
Summary
Component based software development (CBSD) that aims at constructing new systems by compositing prefabricated reusable components have been tested can shorten the development cycle and improve software quality [1]. (2015) Software Components Behavioral Adaptation Based on LTS. C. Zhang tem [3] (LTS) has graphical property and has strict mathematic foundation so be selected to model component behavioral. The first step of adaption process is to define the corresponding actions between sender and receiver as synchronous vectors. Analyze different mismatch types and adaptation strategies and design the adaptation algorithm to build adaptor specification automatically to ensure the correct interaction between the components with mismatch behavioral.
