This class
provides a protocol for determining values based on dates according to derived implementations of specific day-count conventions.

pure virtual |
Return the (signed) number of days between the specified beginDate
and endDate
. If beginDate <= endDate
, then the result is non-negative. Note that reversing the order of beginDate
and endDate
negates the result.
Implemented in bbldc::BasicBasicDayCountAdapter< CONVENTION >, and bbldc::TerminatedBasicDayCountAdapter< CONVENTION >.

pure virtual |
Return the (signed fractional) number of years between the specified beginDate
and endDate
. If beginDate <= endDate
, then the result is non-negative. Note that reversing the order of beginDate
and endDate
negates the result; specifically, |yearsDiff(b, e) + yearsDiff(e, b)| <= 1.0e-15
for all dates b
and e
.
Implemented in bbldc::BasicBasicDayCountAdapter< CONVENTION >, and bbldc::TerminatedBasicDayCountAdapter< CONVENTION >.
