详细描述

Constructor for a Loopback connection that will basically just pass messages between objects that are connected to it. It offers no external connections, via IP or any other mechanism. It is useful if you want to make the client and server in the same connection and you don't need to have anything else connect.

构造及析构函数说明

◆ vrpn_Connection_Loopback()

vrpn_Connection_Loopback ( )

protected

Make a client connection. To access this from user code, call vrpn_create_server_connection() with a service name of 'loopback:'. For now, we don't enable logging on a Loopback connection.

成员函数说明

◆ connected()

virtual vrpn_bool connected ( void ) const

inlinevirtual

Returns vrpn_true if the connection has been established, vrpn_false if not (For a networkless connection, this is equivalent to doing_okay()).

重载 vrpn_Connection .

◆ doing_okay()

virtual vrpn_bool doing_okay ( void ) const

inlinevirtual

Returns vrpn_true if the connection is okay, vrpn_false if not

重载 vrpn_Connection .

◆ mainloop()

virtual int mainloop ( const struct timeval * timeout = NULL )

virtual

Call each time through program main loop to handle receiving any incoming messages and sending any packed messages. Returns -1 on error, 0 otherwise. Optional argument is TOTAL time to block on select() calls; there may be multiple calls to select() per call to mainloop(), and this timeout will be divided evenly between them.

实现了 vrpn_Connection.

◆ send_pending_reports()

virtual int send_pending_reports ( void )

inlineprotectedvirtual

send pending report, clear the buffer.

This function was protected, now is public, so we can use it to send out intermediate results without calling mainloop

实现了 vrpn_Connection.

友元及相关符号说明

◆ vrpn_create_server_connection

VRPN_API vrpn_Connection * vrpn_create_server_connection	(	const char *	cname,
		const char *	local_in_logfile_name = NULL,
		const char *	local_out_logfile_name = NULL )

friend

Create a server connection of arbitrary type (VRPN UDP/TCP, TCP, File, Loopback, MPI).

Returns NULL if the name is not understood or the connection cannot be created. WARNING: May not be thread safe. To create a VRPN TCP/UDP server, use a name like: vrpn:machine_name_or_ip:port machine_name_or_ip:port machine_name_or_ip :port (This port on any network card.) To create an MPI server, use a name like: mpi:MPI_COMM_WORLD mpi:comm_number When done with the object, call removeReference() on it (which will delete it if there are no other references).
