<div class="block">A Wire Admin Event.
<p>
<code>WireAdminEvent</code> objects are delivered to all registered
<code>WireAdminListener</code> service objects which specify an interest in the
<code>WireAdminEvent</code> type. Events must be delivered in chronological order
with respect to each listener. For example, a <code>WireAdminEvent</code> of type
<a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_CONNECTED"><code>WIRE_CONNECTED</code></a> must be delivered before a <code>WireAdminEvent</code> of
type <a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_DISCONNECTED"><code>WIRE_DISCONNECTED</code></a> for a particular <code>Wire</code> object.
<p>
A type code is used to identify the type of event. The following event types
are defined:
<ul>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_CREATED"><code>WIRE_CREATED</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_CONNECTED"><code>WIRE_CONNECTED</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_UPDATED"><code>WIRE_UPDATED</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_TRACE"><code>WIRE_TRACE</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_DISCONNECTED"><code>WIRE_DISCONNECTED</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_DELETED"><code>WIRE_DELETED</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#PRODUCER_EXCEPTION"><code>PRODUCER_EXCEPTION</code></a></li>
<li><a href="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#CONSUMER_EXCEPTION"><code>CONSUMER_EXCEPTION</code></a></li>
</ul>
Additional event types may be defined in the future.
<p>
Event type values must be unique and disjoint bit values. Event types must be
defined as a bit in a 32 bit integer and can thus be bitwise OR'ed together.
<p>
Security Considerations. <code>WireAdminEvent</code> objects contain <code>Wire</code>
objects. Care must be taken in the sharing of <code>Wire</code> objects with other
bundles.</div>
