Detailed Description

Defines a factory that actively connects to a remote IP address and TCP port, creating a new ACE_SOCK_Stream object.

The ACE_SOCK_Connector doesn't have a socket of its own, i.e., it simply "borrows" the one from the ACE_SOCK_Stream that's being connected. The reason for this is that the underlying socket API doesn't use a factory socket to connect data mode sockets. Therefore, there's no need to inherit ACE_SOCK_Connector from ACE_SOCK. A nice side-effect of this is that ACE_SOCK_Connector objects do not store state so they can be used reentrantly in multithreaded programs.

Constructor & Destructor Documentation

ACE_SOCK_Connector::ACE_SOCK_Connector ( void )

inline

Default constructor.

ACE_SOCK_Connector::ACE_SOCK_Connector	(	ACE_SOCK_Stream &	new_stream,
		const ACE_Addr &	remote_sap,
		const ACE_Time_Value *	timeout = `0`,
		const ACE_Addr &	local_sap = `ACE_Addr::sap_any`,
		int	reuse_addr = `0`,
		int	flags = `0`,
		int	perms = `0`,
		int	protocol = `0`
	)

Actively connect to a peer, producing a connected ACE_SOCK_Stream object if the connection succeeds.

Parameters

new_stream	The `ACE_SOCK_Stream` object that will be connected to the peer.
remote_sap	The address that we are trying to connect to. The protocol family of `remote_sap` is used for the connected socket. That is, if `remote_sap` contains an IPv6 address, a socket with family PF_INET6 will be used, else it will be PF_INET.
timeout	Pointer to an `ACE_Time_Value` object with amount of time to wait to connect. If the pointer is 0 then the call blocks until the connection attempt is complete, whether it succeeds or fails. If timeout == {0, 0} then the connection is done using nonblocking mode. In this case, if the connection can't be made immediately, this method returns -1 and errno == EWOULDBLOCK. If timeout > {0, 0} then this is the maximum amount of time to wait before timing out; if the specified amount of time passes before the connection is made, this method returns -1 and errno == ETIME. Note the difference between this case and when a blocking connect is attempted that TCP times out - in the latter case, errno will be ETIMEDOUT.
local_sap	(optional) The local address to bind to. If it's the default value of `ACE_Addr::sap_any` then the OS will choose an unused port.
reuse_addr	(optional) If the value is 1, the local address (`local_sap`) is reused, even if it hasn't been cleaned up yet.
flags	Ignored.
perms	Ignored.
protocol	(optional) If value is 0, default SOCK_STREAM protocol is selected by kernel (typically TCP).

ACE_SOCK_Connector::ACE_SOCK_Connector	(	ACE_SOCK_Stream &	new_stream,
		const ACE_Addr &	remote_sap,
		ACE_QoS_Params	qos_params,
		const ACE_Time_Value *	timeout = `0`,
		const ACE_Addr &	local_sap = `ACE_Addr::sap_any`,
		ACE_Protocol_Info *	protocolinfo = `0`,
		ACE_SOCK_GROUP	g = `0`,
		u_long	flags = `0`,
		int	reuse_addr = `0`,
		int	perms = `0`
	)

Actively connect to a peer, producing a connected ACE_SOCK_Stream object if the connection succeeds.

Parameters

new_stream	The `ACE_SOCK_Stream` object that will be connected to the peer.
remote_sap	The address that we are trying to connect to. The protocol family of `remote_sap` is used for the connected socket. That is, if `remote_sap` contains an IPv6 address, a socket with family PF_INET6 will be used, else it will be PF_INET.
qos_params	Contains QoS parameters that are passed to the IntServ (RSVP) and DiffServ protocols.

See also: ACE_QoS_Params.

Parameters

timeout	Pointer to an `ACE_Time_Value` object with amount of time to wait to connect. If the pointer is 0 then the call blocks until the connection attempt is complete, whether it succeeds or fails. If timeout == {0, 0} then the connection is done using nonblocking mode. In this case, if the connection can't be made immediately, this method returns -1 and errno == EWOULDBLOCK. If timeout > {0, 0} then this is the maximum amount of time to wait before timing out; if the specified amount of time passes before the connection is made, this method returns -1 and errno == ETIME. Note the difference between this case and when a blocking connect is attempted that TCP times out - in the latter case, errno will be ETIMEDOUT.
local_sap	(optional) The local address to bind to. If it's the default value of `ACE_Addr::sap_any` then the OS will choose an unused port.
reuse_addr	(optional) If the value is 1, the local address (`local_sap`) is reused, even if it hasn't been cleaned up yet.
flags	Ignored.
perms	Ignored.

ACE_SOCK_Connector::~ACE_SOCK_Connector ( void )

Member Function Documentation

int ACE_SOCK_Connector::complete	(	ACE_SOCK_Stream &	new_stream,
		ACE_Addr *	remote_sap = `0`,
		const ACE_Time_Value *	timeout = `0`
	)

Try to complete a nonblocking connection that was begun by a previous call to connect with a {0, 0} ACE_Time_Value timeout.

See also: connect().

Parameters

new_stream	The `ACE_SOCK_Stream` object that will be connected to the peer.
remote_sap	If non-0, it points to the `ACE_INET_Addr` object that will contain the address of the connected peer.
timeout	Same values and return value possibilites as for connect().
