org.osgi.service.wireadmin.WireAdminEvent

A Wire Admin Event.

{@code WireAdminEvent} objects are delivered to all registered{@code WireAdminListener} service objects which specify an interest in the{@code WireAdminEvent} type. Events must be delivered in chronological orderwith respect to each listener. For example, a {@code WireAdminEvent} of type{@link #WIRE_CONNECTED} must be delivered before a {@code WireAdminEvent} oftype {@link #WIRE_DISCONNECTED} for a particular {@code Wire} object.

A type code is used to identify the type of event. The following event types are defined:

{@link #WIRE_CREATED}
{@link #WIRE_CONNECTED}
{@link #WIRE_UPDATED}
{@link #WIRE_TRACE}
{@link #WIRE_DISCONNECTED}
{@link #WIRE_DELETED}
{@link #PRODUCER_EXCEPTION}
{@link #CONSUMER_EXCEPTION}

Additional event types may be defined in the future.

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.

Security Considerations. {@code WireAdminEvent} objects contain {@code Wire}objects. Care must be taken in the sharing of {@code Wire} objects with otherbundles. @see WireAdminListener @Immutable @author $Id: 665e72cdd3f4fa7a4c56e01da3e9a1b589025a46 $
