Detailed Description

Represents a single TCP or UDP socket for input or output.

Definition at line 45 of file connection.h.

Constructor & Destructor Documentation

Connection::Connection (  ConnectionManager *  manager,
PRFileDesc *  socket
) 
 

Creates a connection.

Normally this constructor should not be used directly by user code; use one of the methods in ConnectionManager to make a new connection.

Connection::~Connection (   ) 
 

Closes a connection.

Definition at line 68 of file connection.cxx.

int ReferenceCount::ref (   )  const [inline, inherited]
 

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.

bool Connection::send_datagram (  const NetDatagram &  datagram  )  [private]
 

This method is intended only to be called by ConnectionWriter.

It atomically writes the given datagram to the socket, returning true on success, false on failure. If the socket seems to be closed, it notifies the ConnectionManager.

bool Connection::send_raw_datagram (  const NetDatagram &  datagram  )  [private]
 

This method is intended only to be called by ConnectionWriter.

It atomically writes the given datagram to the socket, without the Datagram header.

void Connection::set_collect_tcp (  bool  collect_tcp  ) 
 

Enables or disables "collect-tcp" mode.

In this mode, individual TCP packets are not sent immediately, but rather they are collected together and accumulated to be sent periodically as one larger TCP packet. This cuts down on overhead from the TCP/IP protocol, especially if many small packets need to be sent on the same connection, but it introduces additional latency (since packets must be held before they can be sent).

See set_collect_tcp_interval() to specify the interval of time for which to hold packets before sending them.

If you enable this mode, you may also need to periodically call consider_flush() to flush the queue if no packets have been sent recently.

Definition at line 175 of file connection.cxx.

void Connection::set_collect_tcp_interval (  double  interval  ) 
 

Specifies the interval in time, in seconds, for which to hold TCP packets before sending all of the recently received packets at once.

This only has meaning if "collect-tcp" mode is enabled; see set_collect_tcp().

void Connection::set_keep_alive (  bool  flag  ) 
 

Sets whether the connection is periodically tested to see if it is still alive.

Definition at line 353 of file connection.cxx.

References _socket, _write_mutex, DatagramUDPHeader::get_header(), Datagram::get_message(), nassertr, and NULL.

void Connection::set_linger (  bool  flag,
double  time
) 
 

Sets the time to linger on close if data is present.

If flag is false, when you close a socket with data available the system attempts to deliver the data to the peer (the default behavior). If flag is false but time is zero, the system discards any undelivered data when you close the socket. If flag is false but time is nonzero, the system waits up to time seconds to deliver the data.

Definition at line 318 of file connection.cxx.

void Connection::set_max_segment (  int  size  ) 
 

Sets the maximum segment size.

References INLINE.

Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref (   )  const [inline, inherited]
 

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.
