Detailed Description

Abstract base class for application raw socket handlers registered with AsyncComm.

Allows applications to register a socket with the AsyncComm polling mechanism and perform raw event handling on the socket.

Member Function Documentation

virtual void Hypertable::RawSocketHandler::deregister ( int  sd )

pure virtual

Deregister handler for a given socket.

This method is called by the communication layer after the socket has been removed from the polling mechanism.

Parameters

sd	Socket descripter that was deregistered

Implemented in Hypertable::SshSocketHandler.

virtual bool Hypertable::RawSocketHandler::handle ( int  sd, int  events  )

pure virtual

Handle socket event.

Parameters

sd	Socket descriptor
events	Bitmask of polling events

See also

PollEvent::Flags

Implemented in Hypertable::SshSocketHandler.

virtual int Hypertable::RawSocketHandler::poll_interest ( int  sd )

pure virtual

Returns desired polling interest for a socket.

This method returns the current polling interest for socket sd. After calling handle(), the communication layer will call this method to obtain the polling interest for sd and will make the appropriate adjustments with the underlying polling mechanism.

Parameters

sd	Socket descriptor

Returns

Bitmask of desired polling interest for sd.

PollEvent::Flags

Implemented in Hypertable::SshSocketHandler.
