+/// @brief Holds configuration parameters pertaining to lease expiration
+/// and lease affinity.
+///
+/// This class holds the values of the following configuration parameters:
+///
+/// - reclaim-timer-wait-time - is the time between two cycles of processing
+///   expired leases, expressed in seconds, i.e. the time between the end of
+///   one cycle and the beginning of the next cycle. If this value is 0, the
+///   expired leases are not processed.
+///
+/// - flush-reclaimed-timer-wait-time - is the time between two cycles of
+///   recycling "expired-reclaimed" leases, expressed in seconds. If this
+///   value is 0, the expired leases are removed by the leases reclamation
+///   routine rather than recycling function. The recycling function is not
+///   executed and the value of the "hold-reclaimed-time" is ignored.
+///
+/// - hold-reclaimed-time -is the time for which "expired-reclaimed" leases
+///   are held in the lease database in the "expired-reclaimed" state after
+///   they expire. If this time is set to 0, the recycling function is not
+///   executed and the value of the "recycle-timer-wait-time" is ignored.
+///   This value is expressed in seconds.
+///
+/// - max-reclaim-leases - is the maximum number of leases to be processed
+///   in a single cycle. If this value is 0, all expired leases are
+///   processed in a single cycle, unless the maximum processing time
+///   (configured with the "max-time") parameter elapses first.
+///
+/// - max-reclaim-time - the maximum time that a single processing cycle
+///   may last, expressed in milliseconds. If this value is 0, there is no
+///   limitation for the maximum processing time. This value is expressed
+///   in milliseconds.
+///
+/// - unwarned-reclaim-cycles - is the number of consecutive processing
+///   cycles of expired leases, after which the system issues a warning if
+///   there are still expired leases in the database. If this value is 0,
+///   the warning is never issued.
+///

+/// modifiers to manage the data. Each accessor checks if the given value
