The core event management system.
This defines all the different types of file descriptors that can be used by the SelectServer. At the top level, the ReadFileDescriptor / WriteFileDescriptor interfaces provide the minimum functionality needed to register a socket with the SelectServer to handle read / write events. The BidirectionalFileDescriptor extends this interface to handle both reading and writing.
The UnmanagedFileDescriptor allows socket descriptors created by other libraries to be used with the SelectServer.
ConnectedDescriptor is a socket with tighter integration with the SelectServer. This allows the SelectServer to detect when the socket is closed and call the OnClose() handler. It also provides methods to disable SIGPIPE, control the blocking attributes and check how much data remains to be read. ConnectedDescriptor has the following sub-classes:
