Detailed Description

template<typename Derived, typename IFACE, typename BASE = L4::Server_object>
struct L4::Server_object_x< Derived, IFACE, BASE >

Helper class to implement p_dispatch based server objects.

Template Parameters
DerivedThe data type of your server object class.
IFACEThe data type providing the interface definition for the object.
BASEOptional data-type of the base server object (usually L4::Server_object)

This class implements the standard dispatch() function of L4::Server_object and forwards incoming messages to a set of overloaded p_dispatch() functions. There must be a p_dispatch() function in Derived for each interface provided by IFACE with the signature

int p_dispatch(Iface *, unsigned rights, L4::Ipc::Iostream &)

that is called for messages with protocol == Iface::Protocol.

Example signature for L4Re::Dataspace is:

int p_dispatch(L4Re::Dataspace *, unsigned, L4::Ipc::Iostream &)
