Context

A context is a set of peers which are able to communicate with each other. A context need to be defined by a communication policy, since every communication library defines a set of peers differently. The cage defines a strict interface of a context, but the implementation is left open to the communication policy.

The following listing provides a skeleton for a context class with all necessary methods:

struc ContextSkeleton {

    // Returns the number of peers in this context
    size_t size() const {...}

    // Returns the virtual address of the peer in this context
    VAddr getVAddr() const {...}

    // Returns the id of this context
    ContextID getID() const {...}

    // Returns whether the peer is member of the context
    bool valid() const {...}

};
