# OECreateFastFPDatabaseOptions¶

class OECreateFastFPDatabaseOptions


This class represents the OECreateFastFPDatabaseOptions class that encapsulates properties that determine how fast fingerprints are generated when calling the OECreateFastFPDatabaseFile function.

## Constructors¶

OECreateFastFPDatabaseOptions(const OEFPTypeBase *fptype)


Constructs an OECreateFastFPDatabaseOptions object with the given fingerprints type.

Note

GraphSim TK currently only supports the popcount search method for fingerprints with the size of multiple of 256. This means that the OEFPType.MACCS166 fingerprint type is currently not supported. When using other custom fingerprint types (see User-defined Fingerprint section) the size of the fingerprint must be a multiple of 256 in order to be able to search it with the popcount method.

## GetFPType¶

const OEFPTypeBase *GetFPType() const


Returns the fingerprint type in which the OECreateFastFPDatabaseOptions was constructed.

## GetNumProcessors¶

unsigned int GetNumProcessors() const


Returns the number of threads that are used to generate fingerprints when calling the OECreateFastFPDatabaseFile function.

## SetNumProcessors¶

void SetNumProcessors(unsigned int nrps)


Sets the number of threads that are used to generate fingerprints when calling the OECreateFastFPDatabaseFile function. When set to 0, the number of processors used will be the number returned by the OEGetNumProcessors function.

## SetTracer¶

void SetTracer(const OESystem::OEDots &dots)


Sets a tracer that can be used to show the progress of fingerprint generation.
