	Get the server description of this connection.
void	SetDescription (std::string desc)
	Set the server description of this connection.
int	GetServerPort ()
	Get the port number being used for this connection If the connection is outbound this will be the remote port otherwise it will be the local port, so it can always be gautanteed as open at the address given in GetServerIP().

void	ClearBuffer ()
	This method clears the server's buffer by setting it to an empty string.
std::string	GetBuffer ()
	This method retrieves the first string from the tail end of the buffer and advances the tail end of the buffer past the returned string, in a similar manner to strtok().

Detailed Description

Each connection has one or more of these each represents ONE outbound connection to another ircd so each inbound has multiple outbounds.

A listening socket that accepts server type connections is represented by one class serverrec. Class serverrec will instantiate several objects of type ircd_connector to represent each established connection, inbound or outbound. So, to determine all linked servers you must walk through all the serverrecs that the core defines, and in each one iterate through until you find connection(s) relating to the server you want information on. The core and module API provide functions for this.

Member Function Documentation

void ircd_connector::AddBuffer (  std::string  a  )

This method adds text to the ircd connection's buffer There is no limitation on how much text of what line width may be added to this buffer. It is the sending server's responsibility to ensure sent data is kept within reasonable quanities.

bool ircd_connector::BufferIsComplete (   )

This method returns true if the buffer contains at least one carriage return character, e.g. one line can be read from the buffer successfully.

void ircd_connector::ClearBuffer (   )

This method clears the server's buffer by setting it to an empty string.

void ircd_connector::CloseConnection (   )

Close the connection by calling close() on its file descriptor This function call updates no other data.

std::string ircd_connector::GetBuffer (   )

This method retrieves the first string from the tail end of the buffer and advances the tail end of the buffer past the returned string, in a similar manner to strtok().

std::string ircd_connector::GetDescription (   )

Get the server description of this connection.

int ircd_connector::GetDescriptor (   )

Get the file descriptor associated with this connection.

char* ircd_connector::GetServerIP (   )

Get the ip address (not servername) associated with this connection.

std::string ircd_connector::GetServerName (   )

Return the servername on this established connection.

int ircd_connector::GetServerPort (   )

Get the port number being used for this connection If the connection is outbound this will be the remote port otherwise it will be the local port, so it can always be gautanteed as open at the address given in GetServerIP().

int ircd_connector::GetState (   )

Get the state flags for this connection.

std::string ircd_connector::GetVersionString (   )

This method returns the version string of the remote server. If the server has no version string an empty string is returned.

bool ircd_connector::MakeOutboundConnection (  char *  newhost, int  newport )

Create an outbound connection to a listening socket.

void ircd_connector::SetDescription (  std::string  desc  )

Set the server description of this connection.

void ircd_connector::SetDescriptor (  int  fd  )

Set the file descriptor for this connection.

bool ircd_connector::SetHostAddress (  char *  host, int  port )  [private]

PRIVATE function to set the host address and port to connect to.

bool ircd_connector::SetHostAndPort (  char *  newhost, int  newport )

Set both the host and the port in one operation for this connection.

void ircd_connector::SetServerName (  std::string  serv  )

Set the server name of this connection.

void ircd_connector::SetServerPort (  int  p  )

Set the port used by this connection.

void ircd_connector::SetState (  int  state  )

Set the state flags for this connection.

void ircd_connector::SetVersionString (  std::string  newversion  )

This method sets the version string of the remote server.
