Returns an array containing all the NSConnection objects known to the system. These connections will be valid at the time that the array was created, but may be invalidated by other threads before you get to examine the array.

Returns a connection initialised using -initWithReceivePort:sendPort:
Both ports must be of the same type.

Returns an NSConnection object whose send port is that of the NSConnection registered under the name n on the host h

This method calls +connectionWithRegisteredName:host:usingNameServer: using the default system name server.

Use NSSocketPortNameServer for connections to remote hosts.

Returns an NSConnection object whose send port is that of the NSConnection registered under name on host.

The nameserver server is used to look up the send port to be used for the connection.
Use [NSSocketPortNameServer +sharedInstance] for connections to remote hosts.

If host is nil or an empty string, the host is taken to be the local machine.
If it is an asterisk ('*') then the nameserver checks all hosts on the local subnet (unless the nameserver is one that only manages local ports).
In the GNUstep implementation, the local host is searched before any other hosts.
NB. if the nameserver does not support connections to remote hosts (the default situation) the host argeument should be omitted.

If no NSConnection can be found for name and host host, the method returns nil.

The returned object has the default NSConnection of the current thread as its parent (it has the same receive port as the default connection).

Return the current conversation... not implemented in GNUstep

Returns the default connection for a thread.
Creates a new instance if necessary.
The default connection has a single NSPort object used for both sending and receiving - this it can't be used to connect to a remote process, but can be used to vend objects.
Possible problem - if the connection is invalidated, it won't be cleaned up until this thread calls this method again. The connection and it's ports could hang around for a very long time.

This method calls +rootProxyForConnectionWithRegisteredName:host:usingNameServer: to return a proxy for a root object on the remote connection with the send port registered under name n on host h.

This method calls +connectionWithRegisteredName:host:usingNameServer: to get a connection, then sends it a -rootProxy message to get a proxy for the root object being vended by the remote connection. Returns the proxy or nil if it couldn't find a connection or if the root object for the connection has not been set.
Use [NSSocketPortNameServer +sharedInstance] for connections to remote hosts.

Adds mode to the run loop modes that the NSConnection will listen to for incoming messages.

Adds loop to the set of run loops that the NSConnection will listen to for incoming messages.

Returns the delegate of the NSConnection.

Sets the NSConnection configuration so that multiple threads may use the connection to send requests to the remote connection.
This option is inherited by child connections.
NB. A connection with multiple threads enabled will run slower than a normal connection.

Returns YES if the NSConnection is configured to handle remote messages atomically, NO otherwise.
This option is inherited by child connections.

Initialises an NSConnection with the receive port r and the send port s.
Behavior varies with the port values as follows -

r is nil

The NSConnection is released and the method returns nil.

s is nil

The NSConnection uses r as the send port as well as the receive port.

s is the same as r

The NSConnection is usable only for vending objects.

A connection with the same ports exists

The new connection is released and the old connection is retained and returned.

A connection with the same ports (swapped) exists

The new connection is initialised as normal, and will communicate with the old connection.

If a connection exists whose send and receive ports are both the same as the new connections receive port, that existing connection is deemed to be the parent of the new connection. The new connection inherits configuration information from the parent, and the delegate of the parent has a chance to adjust the configuration of the new connection or veto its creation.
NSConnectionDidInitializeNotification is posted once a new connection is initialised.

Marks the receiving NSConnection as invalid.
Removes the NSConnections ports from any run loops.
Posts an NSConnectionDidDieNotification.
Invalidates all remote objects and local proxies.

Returns YES if the connection is valid, NO otherwise. A connection is valid until it has been sent an -invalidate message.

Returns an array of all the local objects that have proxies at the remote end of the connection because they have been sent over the connection and not yet released by the far end.

Returns YES if the connection permits multiple threads to use it to send requests, NO otherwise.
See the -enableMultipleThreads method.

Returns the NSPort object on which incoming messages are received.

Simply invokes -registerName:withNameServer: passing it the default system nameserver.

Registers the receive port of the NSConnection as name and unregisters the previous value (if any).
Returns YES on success, NO on failure.
On failure, the connection remains registered under the previous name.
Supply nil as name to unregister the NSConnection.

Returns an array of proxies to all the remote objects known to the NSConnection.

Removes mode from the run loop modes used to receive incoming messages.

Removes loop from the run loops used to receive incoming messages.

Returns the timeout interval used when waiting for a reply to a request sent on the NSConnection. This value is inherited from the parent connection or may be set using the -setReplyTimeout: method.
The default value is the maximum delay (effectively infinite).

Returns an array of all the run loop modes that the NSConnection uses when waiting for an incoming request.

Returns the timeout interval used when trying to send a request on the NSConnection. This value is inherited from the parent connection or may be set using the -setRequestTimeout: method.
The default value is the maximum delay (effectively infinite).

Returns the object that is made available by this connection or by its parent (the object is associated with the receive port).
Returns nil if no root object has been set.

Returns the proxy for the root object of the remote NSConnection.
Generally you will wish to call [NSDistantObject -setProtocolForProxy:] immediately after obtaining such a root proxy.

Removes the NSConnection from the current threads default run loop, then creates a new thread and runs the NSConnection in it.

Returns the port on which the NSConnection sends messages.

Sets the NSConnection's delegate (without retaining it).
The delegate is able to control some of the NSConnection's behavior by implementing methods in an informal protocol.

Sets whether or not the NSConnection should handle requests arriving from the remote NSConnection atomically.
By default, this is set to NO... if set to YES then any messages arriving while one message is being dealt with, will be queued.
NB. careful - use of this option can cause deadlocks.

Sets the time interval that the NSConnection will wait for a reply for one of its requests before raising an NSPortTimeoutException.
NB. In GNUstep you may also get such an exception if the connection becomes invalidated while waiting for a reply to a request.

Sets the runloop mode in which requests will be sent to the remote end of the connection. Normally this is NSDefaultRunloopMode

Sets the time interval that the NSConnection will wait to send one of its requests before raising an NSPortTimeoutException.

Sets the root object that is vended by the connection.

Returns an object containing various statistics for the NSConnection.
On GNUstep the dictionary contains -

NSConnectionRepliesReceived

The number of messages replied to by the remote NSConnection.

NSConnectionRepliesSent

The number of replies sent to the remote NSConnection.

NSConnectionRequestsReceived

The number of messages received from the remote NSConnection.

NSConnectionRequestsSent

The number of messages sent to the remote NSConnection.

NSConnectionLocalCount

The number of local objects currently vended.

NSConnectionProxyCount

The number of remote objects currently in use.

This is not an NSConnection method, but is a method that may be implemented by the delegate of an NSConnection object.

If the delegate implements this method, the NSConnection will invoke the method for every message request or reply it receives from the remote NSConnection. The delegate should use the authentication data to check all the NSData objects in the components array (ignoring NSPort objects), and return YES if they are valid, NO otherwise.

If the method returns NO then an NSFailedAuthentication exception will be raised.

In GNUstep the components array is mutable, allowing you to replace the NSData objects with your own version.

This is not an NSConnection method, but is a method that may be implemented by the delegate of an NSConnection object.

If the delegate implements this method, the NSConnection will invoke the method for every message request to reply it sends to the remote NSConnection. The delegate should generate authentication data by examining all the NSData objects in the components array (ignoring NSPort objects), and return the authentication data that can be used by the remote NSConnection.

If the method returns nil then an NSGenericException exception will be raised.

In GNUstep the components array is mutable, allowing you to replace the NSData objects with your own version.

Description forthcoming.

This is not an NSConnection method, but is a method that may be implemented by the delegate of an NSConnection object.

If the delegate implements this method, it will be called whenever a new NSConnection is created that has this NSConnection as its parent. The delegate may take this opportunity to adjust the configuration of the new connection and may return a boolean value to tell the parent whether the creation of the new connection is to be permitted or not.

An old fashioned synonym for -connection:shouldMakeNewConnection: - don't use this.
