matchKnownItem()

template<typename PrefilledItemType , typename Adapter , typename ItemCompare >

int ShortIdProcessor< PrefilledItemType, Adapter, ItemCompare >::matchKnownItem ( uint64_t  shortid, const ItemType &  item  )

inline

Attempts to add a known item by matching its shortid with the supplied ones.

The shortids must be processed prior from calling this method.

Parameters

[in]	shortid	The shortid of the item
[in]	item	The item to be added, whose index is retrieved from its shortid

Returns

int The number of added items:

• 0 if it was not added (e.g. index out of bounds).
• +1 if added successfully.
• -1 if an existing item was removed due to collision.
