Detailed Description

Helper class for performing raw socket IO.

This class abstracts an interface to an external helper which which facilitates binary IO on a connection (for implementing WebSockets). In order to use raw IO, one first has to register an instance of this class using SetRawSocketHandler() and then produce a HttpResponse code 101. After sending this HttpResponse, EHS switches the corresponding connection into raw Mode, which does no further message parsing on received data, but invokes the OnData method whenever data arrives from the client.

Examples:

ehs_wsgate.cpp.

Member Function Documentation

virtual void OnConnect

(

EHSConnection *

conn

)

[pure virtual]

Handle connect event.

Called by EHS, if an EHSConnection has switched into raw mode.

Parameters:

conn	The EHSConnection on which the event has happened.

virtual bool OnData	(	EHSConnection *	conn,
		std::string	data
	)		[pure virtual]

Handle raw data.

Called by EHS, if an EHSConnection is in raw mode.

Parameters:

conn	The EHSConnection on which the data was received.
data	The received data.

Returns:

true, if the connection should be kept open.

virtual void OnDisconnect

(

EHSConnection *

conn

)

[pure virtual]

Handle disconnect event.

Called by EHS, if an EHSConnection is about to be closed.

Parameters:

conn	The EHSConnection on which the event has happened.
