- The senf::FileHandle class is the base of a hierarchy of socket
- handle classes (realized as templates). These classes provide an
- interface to the complete socket API. While going down the
- inheritance hierarchy, the interface will be more and more
- complete.
-
- The most complete interface is provided by
- senf::ProtocolClientSocketHandle and
- senf::ProtocolServerSocketHandle. The template Arguments specifies
- the Protocol class of the underlying socket type. These are the
- \e only classes having public constructors and are therefore the
- only classes, which may be created by the library user. You will
- normally use these classes by naming a specific socket typedef
- (e.g. senf::TCPv4ClientSocketHandle).
-
- However, to aid writing flexible and generic code, the socket
- library provides the senf::ClientSocketHandle and
- senf::ServerSocketHandle class templates. These templates
- implement a family of closely related classes based on the
- specification of the socket policy. This policy specification may
- be \e incomplete (see below). Instances of
- senf::ClientSocketHandle/senf::ServerSocketHandle can be assigned
- and converted to different ClientSocketHandle/ServerSocketHandle
- types as long as the policy specifications are compatible.
-
- \attention It is very important, to (almost) always pass the socket
- handle <em>by value</em>. The socket handle is a very lightweight
- class and designed to be used like an ordinary built-in type. This
- is very important in combination with the policy interface.
-
- \note The FileHandle hierarchy below the SocketHandle template is
- \e not meant to be user extensible. To add new socket types, you
- should introduce new protocol and/or policy classes, the
- SocketHandle classes should not be changed.
