Detailed Description

Base index interface.

You may think of index as some data structure optimized for search queries.

Member Function Documentation

virtual ResultValue<FSDKError, int> fsdk::IIndex::search ( const IDescriptor *  reference, int  maxResultsCount, SearchResult *  results  ) const

pure virtualnoexcept

Search for descriptors with the shorter distance to passed descriptor.

Parameters

[in]	reference	Descriptor to match against index.
[in]	maxResultsCount	Maximum count of results. It is upper bound value, it does not guarantee to return exactly this amount of results.
[out]	results	C-Array of at least

See Also

maxResultsCount size. Is filled with query results.

Returns

ResultValue with error code and count of found descriptors.
