Examples of javax.sip.header.EventHeader

javax.sip.header.EventHeader
etf.org/rfc/rfc3265.txt">RFC3265, this header is not part of RFC3261.
For the purposes of matching responses and NOTIFY messages with SUBSCRIBE messages, the event-type portion of the "Event" header is compared byte-by-byte, and the "id" parameter token (if present) is compared byte-by-byte. An "Event" header containing an "id" parameter never matches an "Event" header without an "id" parameter. No other parameters are considered when performing a comparison, i.e. "Event: foo; id=1234" would match "Event: foo; param=abcd; id=1234", but not "Event: Foo; id=1234".
There MUST be exactly one event type listed per event header. Multiple events per message are disallowed i.e Subscribers MUST include exactly one "Event" header in SUBSCRIBE requests, indicating to which event or class of events they are subscribing. The "Event" header will contain a token which indicates the type of state for which a subscription is being requested. This token will correspond to an event package which further describes the semantics of the event or event class. The "Event" header MAY also contain an "id" parameter. When a subscription is created in the notifier, it stores the event package name and the "Event" header "id" parameter (if present) as part of the subscription information.
This "id" parameter, if present:
- contains an opaque token which identifies the specific subscription within a dialog.
- is only valid within the scope of a single dialog.
- if contained in the initial SUBSCRIBE message on the "Event" header, then refreshes of the subscription must also contain an identical "id" parameter, they will otherwise be considered new subscriptions in an existing dialog.
- if present in the SUBSCRIBE message, that "id" parameter MUST also be present in the corresponding NOTIFY messages.
If the event package to which the event token corresponds defines behavior associated with the body of its SUBSCRIBE requests or parameters for the Event header, those semantics apply. @author BEA Systems, NIST @version 1.2
