Member Function Documentation

virtual uint64_t fsdk::IDynamicIndex::countOfIndexedDescriptors ( ) const

pure virtualnoexcept

Returns count of indexed descriptors.

You may wonder why this method exists if IDynamicIndex already inherits IStaticDescriptorStorage::size method. The reason is that

See Also

IDynamicDescriptorStorage::removeDescriptor behaves differently on

IIndexBuild and IDynamicIndex. On builder it does actually erases descriptor out of internal storage, but it does not erase it if used on IDynamicIndex. The reason is that graph data structure relies on indexes being constant, so removeDescriptor only removes it out of graph, so it is not discoverable by

IIndex::search. So this methods returns actuall data storage size minus count of removed descriptors.

Returns

Count of indexed descriptors.

virtual Result<FSDKError> fsdk::IDynamicIndex::saveToDenseIndex ( const char *  path ) const

pure virtualnoexcept

Saves index as dense.

To load saved index use

See Also

IFaceEngine::loadDenseIndex method. Dense index cannot be loaded as dynamic.

Parameters

path	Path to file to be created and filled with index data. Any extension is acceptable.

Returns

One of the error codes specified by

See Also

FSDKError.

virtual Result<FSDKError> fsdk::IDynamicIndex::saveToDynamicIndex ( const char *  path ) const

pure virtualnoexcept

Saves index as dynamic.

To load saved index use

See Also

IFaceEngine::loadDynamicIndex method. Dynamic index cannot be loaded as dense.

Parameters

path	Path to file to be created and filled with index data. Any extension is acceptable.

Returns

One of the error codes specified by

See Also

FSDKError.
