Detailed Description

Base class to map to items one a range within a target collection. All items in a target collection must be mapped to one and only one key. The target collection will normally be a RefVector (also PtrVector and std::vector could work) To be used by MultiAssociation. Any other usage beyond MultiAssociation is not supported. This class holds:

• ref_offsets_: A non decreasing list of offsets in the target collection, with one item for each key plus one end item. A range is given by a consecutive pair of offsets. While filling the map, some items can be '-1', but not the last one.
• id_offsets_ : A list of pairs, mapping a product id to its associated range in ref_offsets_ This class can be filled through a FastFiller, that requires to fill keys and offsets in strictly increasing order, and without gaps. Only one FastFiller can exist at time, and each FastFiller fills only for a given key collection.
