|Title:||Typed Connector Families|
|Authors:||José Paiva Proença|
|Abstract:||Typed models of connector/component composition specify interfaces describing ports of components and connectors. Typing ensures that these ports are plugged together appropriately, so that data can flow out of each output port and into an input port. These interfaces typically consider the direction of data flow and the type of values flowing. Components, connectors, and systems are often parameterised in such a way that the parameters affect the interfaces. Typing such connector families is challenging. This paper takes a first step towards addressing this problem by presenting a calculus of connector families with integer and boolean parameters. The calculus is based on monoidal categories, with a dependent type system that describes the parameterised interfaces of these connectors. As an example, we demonstrate how to define n-ary Reo connectors in the calculus. The paper focusses on the structure of connectors—well-connectedness—and less on their behaviour, making it easily applicable to a wide range of coordination and componentbased models. A type-checking algorithm based on constraints is used to analyse connector families, supported by a proof-of-concept implementation. © Springer International Publishing Switzerland 2016.|
