CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe C++ language has only a limited runtime type information system, which doesn’t provide full reflection capabilities. We present a general mechanism to support reflection, exploiting template metaprogramming techniques. Two solutions are presented: a static one where metaclass information is only available at compile time to produce class specific code; and a dynamic one where metaclass objects exist at runtime. As a case study of technique we show how to build an object interface to relational database tables. By just annotating a class definition with meta information, such as storage attributes or index properties of fields, a programmer can define objects that can be stored, fetched or searched in a database table. This approach has been used in building a high-performance, full text search engine.

| Abstract: | The C++ language has only a limited runtime type information system, which doesn’t provide full reflection capabilities. We present a general mechanism to support reflection, exploiting template metaprogramming techniques. Two solutions are presented: a static one where metaclass information is only available at compile time to produce class specific code; and a dynamic one where metaclass objects exist at runtime. As a case study of technique we show how to build an object interface to relational database tables. By just annotating a class definition with meta information, such as storage attributes or index properties of fields, a programmer can define objects that can be stored, fetched or searched in a database table. This approach has been used in building a high-performance, full text search engine. |
