NSConnection objects are used to manage communications between
|
|
|
|
|
objects in different processes, in different machines, or in
|
|
|
|
|
different threads.

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 an NSConnection object whose send port is that of the

NSConnection registered under <em>name</em> on <em>host</em>.

</p>

The nameserver <em>server</em> is used to look up the send
|

|
|
|
port to be used for the connection.

If <em>host</em> is <code>nil</code> 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.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|

If no NSConnection can be found for <em>name</em> and

|
|
<em>host</em>host, the method returns <code>nil</code>.

</p>
|

The returned object has the default NSConnection of the

|
|
current thread as its parent (it has the same receive port
|
|
|
|
|
as the default connection).

both sending and receiving - this it can't be used to

connect to a remote process, but can be used to vend objects.

in the <em>components</em> array (ignoring NSPort objects),

otherwise.

and its use is now deprecated.
