Web Services Conversation Adaptation Using Conditional Substitution Semantics of Application Domain Concepts

Algorithm 4

Adapter automatic generator.

Input: 𝐶𝑃_𝑥 (consuming GAP), 𝐶𝑃_𝑦, Operations Mapping

Matrix Θ.

Output: Source code of the adapter between 𝐶𝑃_𝑥 and

𝐶𝑃_𝑦.

  Begin

  Create an empty class ADAPTER.

  for each operation 𝑂𝑝_(𝑥,𝑖) in 𝐺𝐴𝑃_𝑥  do

   Create a method in ADAPTER with same signature

   as 𝑂𝑝_(𝑥,𝑖).

   Get realizing operations subsequence 𝑂𝑃𝑆𝑒𝑞 from

   𝐶𝑃_𝑦 using Θ.

   Call ConverterGenerator (𝑂𝑝_(𝑥,𝑖) Inputs, 𝑂𝑃𝑆𝑒𝑞 Inputs).

   // Algorithm 2

   if Converter Code generated successfully then

   Add Inputs Converter Code to method body.

   Add invocation Code for 𝑂𝑃𝑆𝑒𝑞 to method body.

   Call ConverterGenerator (𝑂𝑃𝑆𝑒𝑞 Output, 𝑂𝑝_(𝑥,𝑖)

   Outputs).

    if Converter Code generated successfully then

      Add Outputs Converter Code to method body.

    else

      Return Error.

    end if

   else

   Return Error.

   end if

  end for

  Return ADAPTER generated code.
