OEFastROCSHistogram¶
class OEFastROCSHistogram
This class is returned from
OEDBTracer::GetHistogram during and after a
query is sent to OEShapeDatabase::GetScores
or OEShapeDatabase::GetSortedScores. It is
used to contain a list of frequencies representing the distribution
of scores. This same container is used to contain the frequencies
of the following 3 score types:
Constructors¶
OEFastROCSHistogram(size_t numBins=200)
Construct a new histogram with the specified number of “bins” in which to bin the score distribution. The same number of bins is applied to each score type.
OEFastROCSHistogram(const OEFastROCSHistogram &rhs)
Copy constructor for moving a OEFastROCSHistogram in memory.
operator=¶
OEFastROCSHistogram &operator=(const OEFastROCSHistogram &rhs)
Assignment operator for moving a OEFastROCSHistogram in memory.
GetHistogram¶
void GetHistogram(std::vector<unsigned int> &frequencies,
unsigned int scoreType)
Initializes the frequencies vector to the required size to
contain the number of bins for this histogram, then fills it
with the number of molecules that falls within each bin for the
scoreType specified. The scoreType should be one of the following:
GetNumBins¶
size_t GetNumBins() const
Returns the number of bins used for this histogram. The number of bins determines the granularity of the scores.
Update¶
void Update(const OEFastROCSHistogram &rhs)
Sum the histogram rhs into this histogram. This histogram
will then reflect the total of the two histograms. Used for
aggregating histograms during the execution of
OEShapeDatabase::GetScores or
OEShapeDatabase::GetSortedScores.
void Update(const OEShapeDatabaseScore &score)
Updates this histogram from an individual
OEShapeDatabaseScore object usually
representing one molecule during the execution of
OEShapeDatabase::GetScores or
OEShapeDatabase::GetSortedScores.
