// DocMerge from idl: interface com::sun::star::lang::XConnectionPoint
/** supports connection points for connectable objects.
<p>Connectable objects support the following features: </p>
<ul>
<li>outgoing interfaces, such as event sets; </li>
<li>the ability to enumerate the types of the outgoing interfaces;
<li>the ability to connect and disconnect sinks to the object
for those outgoing types; </li>
<li>the ability to enumerate the connections that exist to a
particular outgoing interface. </li>
</ul>
<h4>When to Implement?<h4>
<p>To create a connectable object, you need to implement objects
that provide two related interfaces: </p>
<ul>
<li><type>XConnectionPointContainer</type> </li>
<li><type>XConnectionPoint</type> </li>
</ul>
<p>The <type>XConnectionPointContainer</type> interface is implemented
on the connectable object to indicate the existence of the outgoing
interfaces. It provides a sequence of sub-objects. It also provides
access to all the connection point sub-objects, each of which
implements the <type>XConnectionPoint</type> interface. The
<type>XConnectionPoint</type> interface provides a sequence of
sub-objects. </p>
<p>Each connection point is a separate sub-object to avoid circular
reference counting problems. A connection point controls how many
connections (one or more) it will allow in its implementation of
<member>XConnectionPoint::advise()</member>. </p>
<h4>When to use?</h4>
<p>A client can use the <type>XConnectionPointContainer</type> interface: </p>
<UL>
<LI>to get a sequence of connection points for each outgoing type. </LI>
<LI>to obtain access to connection point sub-objects with the
<type>XConnectionPoint</type> interface for each
outgoing type. Through the XConnectionPoint interface,
a client starts or terminates an advisory loop with the
connectable object and the client's own sink. The
client can also use the <type>XConnectionPoint</type>
interface to get a sequence of the connections that it
knows about. </LI>
</UL>
