Operation
true
to force the explicit service name serialization
for this operation, false
otherwise.
Usually, the method should be overridden if Operation.getServiceName()
is
also overridden, but it was not overridden in the previous HZ version,
i.e. the service name was provided using an explicit external call to
Operation.setServiceName(java.lang.String)
. This mechanism is required to maintain the
backward compatibility of the serialized representation of the operation
since the service name is not serialized if it matches the one returned
by Operation.getServiceName()
.
