NumLib::VectorProvider Class Reference

Detailed Description

Manages storage for vectors.

This interface provides storage management semantics for vectors, which can be acquired at a certain point in time, be released later on and be acquired again etc.

"Released" means that the caller indicates, that he currently does not need that Vector instance, i.e, Either it is not needed anymore for the entire program run, or it is temporarily not needed, but might be acquired again later on. Thereby the implementation of this interface can decide, whether the storage for the specific vector can be freed or reused in the meantime.

All get-methods of this class come in two variants: One with an id argument, and one without. The latter makes it possible to temporarily release a vector during the program run and re-acquire it again. The former variant is intended as a short-cut that simplifies vector acquisition for callers that will use the same vector throughout all of their lifetime without releasing it intermediately.

Attention

The first time a vector is acquired by a method with id argument, the id has to be initialized with zero. The respective method then will set the id to the specific id of the returned vector.
