Detailed Description

The parser interface of the IOAsterisk library.

Constructor & Destructor Documentation

◆ io_asterisk_parser_t()

io_asterisk_parser_t::io_asterisk_parser_t ( )

Constructor initializes parser variables.

◆ ~io_asterisk_parser_t()

virtual io_asterisk_parser_t::~io_asterisk_parser_t ( )

inlinevirtual

Do-nothing destructor.

Member Function Documentation

◆ get_local_address()

virtual const std::string& io_asterisk_parser_t::get_local_address ( ) const

inlinevirtual

Read parser variable local_address, this is the address of the network interface that should listen for incoming connections.

Returns: A string containing the address of the local interface as it was set by the user.

◆ get_local_port()

unsigned short io_asterisk_parser_t::get_local_port ( ) const

virtual

Read parser variable local_port, this is the TCP port that should be used for incoming connections.

Returns: The local tcp port to listen on as it was chosen by the user. The port number is between MIN_TCP_PORT and MAX_TCP_PORT.

◆ set_local_port()

void io_asterisk_parser_t::set_local_port ( unsigned short port )

virtual

Set parser variable local_port.

This is needed when it was set to 0 before: In this case, the OS chooses a free port for the TCP server socket, and the port that it chose has to be published to the user over the parser interface.

Parameters

port	The TCP port number that is currently used. In the range [MIN_TCP_PORT, MAX_TCP_PORT], excluding 0.

Precondition: get_local_port() currently returns 0.

◆ get_server_port_open()

bool io_asterisk_parser_t::get_server_port_open ( ) const

virtual

Return the status of the server port as it is known to the parser.

Returns: false after initialization, or the value most recently set via

See also: set_server_port_open.

◆ set_server_port_open()

void io_asterisk_parser_t::set_server_port_open ( bool open )

virtual

Inform the parser of the current status of the server socket.

Parameters

open	Indicates wether the server socket has just been opened or closed.

Precondition: open may only have the value true if get_server_port_open() currently returns false.

Postcondition

See also: get_server_port_open returns the value of open.

◆ get_connected()

bool io_asterisk_parser_t::get_connected ( ) const

virtual

Return the parser's knowledge concerning wether there currently exists an established sound data TCP connection or not.

Returns: false after initialization, or the value most recently set via

See also: set_connected.

◆ set_connected()

void io_asterisk_parser_t::set_connected ( bool connected )

virtual

Inform the parser about the existance of a sound data connection.

Parameters

connected Indicates wether there currently is a connection or not.

Precondition: connected must not have the same value that is currently returned by

See also: get_connected.

Postcondition

See also: get_connected returns the value of open.

◆ set_new_peer()

void io_asterisk_parser_t::set_new_peer	(	unsigned short	port,
		const std::string &	host
	)

virtual

Set parser monitor variables peer_port and peer_address, and calls set_connected(true).

This method should be called when a new connection is established.

Parameters

port	The TCP port number used by the peer.
host	The Internet host where the peer is located.

Precondition

See also: get_connected currently returns false.

Postcondition

See also: get_connected returns true.

◆ debug()

virtual void io_asterisk_parser_t::debug ( const std::string & message )

inlinevirtual
