In this chapter, the following content will be discussed: Requirements for Koala; Koala interfaces; binding, gluing and switches; the product line architecture; managing versions and variants; subtyping. | Chapter 12 The Koala Component Model Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Overview Requirements for Koala Koala Interfaces Binding, Gluing and Switches The Product Line Architecture Managing Versions and Variants Subtyping Summary Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Koala Koala is architectural description language component model for development of embedded software for consumer electronics products. Is used to build a large diversity of products from a repository of components. Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Requirements for Koala Original requirements: Devise a technique with which components can be ‘freely’ composed into products. The technique must work in resource-constrained environments. Make the product architectures as explicit as possible. Additional requirements: Let components make as few assumptions as . | Chapter 12 The Koala Component Model Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Overview Requirements for Koala Koala Interfaces Binding, Gluing and Switches The Product Line Architecture Managing Versions and Variants Subtyping Summary Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Koala Koala is architectural description language component model for development of embedded software for consumer electronics products.

Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Requirements for Koala Original requirements: Devise a technique with which components can be ‘freely’ composed into products. The technique must work in resource-constrained environments. Make the product architectures as explicit as possible. Additional requirements: Let components make as few assumptions as possible about their environment. Allow for parameterized components that are as efficient as dedicated components. Allow for various ways of connecting components. Page Building Reliable Component-based Systems Chapter 12 - The Koala Component Model Koala Interfaces Provide: Like interfaces in COM and java. Require: Communication with components environment. Multiple: Handle evolution and diversity. Optional: Fine tune.
