<P>
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><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_CONNECTED"><CODE>WIRE_CONNECTED</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_UPDATED"><CODE>WIRE_UPDATED</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_TRACE"><CODE>WIRE_TRACE</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_DISCONNECTED"><CODE>WIRE_DISCONNECTED</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#WIRE_DELETED"><CODE>WIRE_DELETED</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#PRODUCER_EXCEPTION"><CODE>PRODUCER_EXCEPTION</CODE></A>
<li><A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#CONSUMER_EXCEPTION"><CODE>CONSUMER_EXCEPTION</CODE></A>
</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.

This <code>WireAdminEvent</code> type that indicates that an existing wire has

An event is broadcast when <A HREF="../../../../org/osgi/service/wireadmin/WireAdmin.html#deleteWire(org.osgi.service.wireadmin.Wire)"><CODE>WireAdmin.deleteWire(Wire)</CODE></A> is called
with a valid wire. <A HREF="../../../../org/osgi/service/wireadmin/WireAdminEvent.html#getWire()"><CODE>getWire()</CODE></A> will return the

The Consumer object and the Producer object that are associated with the

returned or called to allow synchronous delivery of the events. Both
methods can cause other <code>WireAdminEvent</code> s to take place and
requiring this event to be send before these methods are returned would
mandate asynchronous delivery.
