Jquantlib:327
From MediaWiki
(Redirected from OSGi - Calendar package)
This article opens a discussion about how to implement calendars and related concepts in an OSGi container.
Objectives
We aim to provide interfaces for dates and calendars which cope with certain requirements:
- keep legacy Date and Calendar implementations inherited from QuantLib, given that JQuantLib depends on this legacy code.
- provide convenience interfaces to Jdk Date/Calendar, Joda Date/Calendar
Current status
- Richard produced screenshots from C++ sources: date.cpp and date.hpp
- Zahid is studying C++ sources and comparing against our implementation
Aspects to consider
- Change evaluation date must trigger the notification mechanism which uses the Observer/Observable pattern;
- Performance
Our homework
- Determine which packages and/or classes must be implemented
- Design all OSGi interfaces which must be defined
