Context-Aware Adaptation of Component-Based Systems: An Active Repository Approach

Algorithm 1

The build stage.

//A - list of system’s access interfaces that are not connected

//P - List of system’s provider interfaces

//C - List with the components that are in the repository

S = {}  //solution graph empty in the beginning

while (A  is not empty) do

{

   a = first(A) //removes the first element from A

   if (exists  (c)   in P where c has provider interfaces

      that is compatible with a){

   {

      connect a to its compatible interface in c

      continue

   }

   LC = {c in C where c has provider interfaces compatible with a)

   𝑔_min= min { g(c) of LC }

   𝑔_max = max{ g(c) of LC }

   LCR = { all c in LC where g(c) <= 𝑔_min + alpha * (𝑔_max − 𝑔_min) }

   select a random member v in LCR

   S = S + {v}

   add the provider interfaces from v to P

   add the access interfaces from v to A

}

return S
