Title: Component Composition with Scala
Abstract
Software components that are developed by distinct teams with no
coordination have been traditionally hard to integrate. The difficulty
lies with the fact that the services a component requires in order to
function are usually hard coded in its source code. This entails that
in order to replace one or more of them with different ones, one needs
to change the source code of the original component, which fails to
qualify as "clean" reuse. The Scala programming language addresses this
issue by providing three language concepts, abstract member types,
modular mixin composition and selftype annotations that, combined in a
smart way, allow the programmer to lift the specification of the
required services out of the component code.
In this presentation I will discuss the three concepts listed above
together with some additional presentation of the Scala language and
show how they can be used for component composition by working through
one or two examples, depending on time.
