Detailed Description

This struct keeps general information about a score.

All average statistics are computed by using the total length without rests. If the score is empty (or has only rests), the average polyphony and duration are set to 0.

Parameters

scalar the integer that multiplies these statistics.

Returns: the updated statistics.

Definition at line 156 of file musicutil.h.

ScoreStatistics& ScoreStatistics::operator*= ( const int scalar )

inline

Multiplies all statistics concerning number of notes/chords and length for a integer scalar.

It does not change minimum,maximum and average statistics nor beat type and fifths.

Parameters

scalar the integer that multiplies these statistics.

Returns: these updated statistics.

Definition at line 132 of file musicutil.h.

ScoreStatistics& ScoreStatistics::operator+= ( const ScoreStatistics & addend )

inline

Adds all statistics concerning number of notes/chords and length.

It does not change minimum,maximum and average statistics nor beat type and fifths.

Parameters

addend the statistics that must be added to these.

Returns: these updated statistics.

Definition at line 87 of file musicutil.h.

ScoreStatistics& ScoreStatistics::operator-= ( const ScoreStatistics & subtrahend )

inline

Subtracts all statistics concerning number of notes/chords and length.

It does not change minimum,maximum and average statistics nor beat type and fifths.

Parameters
