<div class="block">Called by the lookupListener's notify() method. Checks the event
sequence number and, based on whether or not a "gap" is found in in
the event sequence, performs lookup (if a gap was found) or
processes the event if no gap was found.
Recall that the Event specification states that if the sequence
numbers of two successive events differ by only 1, then one can be
assured that no events were missed. On the other hand, if the
difference is greater than 1 (the sequence contains a "gap"), then
one or more events may -- or may not -- have been missed. Thus, if a
gap is found in the events, although it's possible that no events
were missed, this method takes the conservative approach by assuming
events were missed. When this method determines that an event may
have been missed, it requests a current "snapshot" of the given
ServiceRegistrar's state by performing lookup.
Since this method can safely assume that no events have been missed
if it finds no gaps in the event sequence, it can safely process
the event maintaining equivalent state to the registrar, that is
finding and filtering new services and filtering updated or changed
existing services.
Note that when a lookup service is discovered, this utility registers
with that lookup service's event mechanism for service events related
to the services of interest. Upon registering with the event
mechanism, a data structure (of type EventReg) containing information
about that registration is placed in a Map for later processing when
events do arrive. If the timing is right, it is possible that a
service event may arrive between the time the registration is made
and the time the EventReg is stored in the map. Thus, this method may
find that the eventRegMap does not contain an element corresponding
to the event this method is currently processing. In that case, this
method will do nothing. It will simply return so that the service
referenced in the event can be discovered using the snapshot returned
by the lookup method that is ultimately c by the
RegisterListenerTask (whose listener registration caused this method
to be invoked in the first place).</div>

<div class="block">With respect to a given service (referenced by the parameter
newItem), if either an event has been received from the given lookup
service (referenced by the proxy parameter), or a snapshot of the
given lookup service's state has been retrieved, this method
determines whether the service's attributes have changed, or whether
a new version of the service has been registered. After the
appropriate determination has been made, this method applies the
filter associated with the current cache and sends the appropriate
local ServiceDiscoveryEvent(s).
This method is called under the following conditions: - when a new
lookup service is discovered, this method will be called for each
previously discovered service - when a gap in the events from a
previously discovered lookup service is discovered, this method will
be called for each previously discovered service - when a MATCH_MATCH
event is received, this method will be called for each previously
discovered service - when a NOMATCH_MATCH event is received, this
method will be called for each previously discovered service Note
that this method is never called when a MATCH_NOMATCH event is
received; such an event is always handled by the handleMatchNoMatch
method.
When this method is called, it may send one of the following events
or combination of events: - a service changed event - a service
removed event followed by a service added event - a service removed
event
A service removed event is sent when the service either fails the
filter, or the filter produces an indefinite result; in which case,
the service is also discarded.
A service changed event is sent when the service passes the filter,
and it is determined that the service's attributes have changed. In
this case, the old and new service proxies are treated as the same if
one of the following conditions is met: - this method was called
because of the receipt of a MATCH_MATCH event - the old and new
service proxies are byte-wise fully equal (Note that the lookup
service specification guarantees that the proxies are the same when a
MATCH_MATCH event is received.)
A service removed event followed by a service added event is sent
when the service passes the filter, and the conditions for which a
service changed event would be considered are not met; that is, this
method was not called because of the receipt of a MATCH_MATCH event;
or the old and new service proxies are not byte-wise fully equal.
The if-else-block contained in this method implements the logic just
described. The parameter matchMatchEvent reflects the pertinent event
state that causes this method to be called. That is, either a
MATCH_MATCH event was received, or it wasn't, (and if it wasn't, then
a full byte-wise comparison is performed to determine whether the
proxies are still the same).
To understand when the 'else' part of the if-else-block is executed,
consider the following conditions: - there is more than one lookup
service with which the service registers (ex. LUS-0 and LUS-1) -
after the service registers with LUS-0, a NOMATCH_MATCH event is
received and handled (so the service is now known to the cache) -
before the service registers with LUS-1, the service is replaced with
a new version - the NOMATCH_MATCH event resulting from the service's
registration with LUS-1 is received BEFORE receiving the
MATCH_NOMATCH/NOMATCH_MATCH event sequence that will ultimately
result from the re-registration of that new version with LUS-0 When
the above conditions occur, the NOMATCH_MATCH event that resulted
from the service's registration with LUS-1 will cause this method to
be invoked and the proxies to be fully compared (because the event
was not a MATCH_MATCH event); and since the old service proxy and the
new service proxy will not be fully equal, the else part of the
if-else-block will be executed.
This method applies the filter only after the above comparisons and
determinations have been completed.</div>
