Mixing COP and OOP

We describe and justify thirteen technical properties that a compo-nent system must possess to work with object-oriented program-ming languages (such as Java, C++, or C#). Our components are designed for large-scale, modular construction of programs with static checking of program compositions. Jiazzi, our enhancement of Java, implements the technical proper-ties that we describe. We use Jiazzi components in our examples, but only to make the discussion more concrete. Readers interested in the details of the Jiazzi component system should refer to our technical paper in OOPSLA ’01 [7]. P1. Language support: Components should be described with a specific language construct. P2. Core language integration: Components should contain, import and export instances of constructs in the core lan-guage
