Member Function Documentation

virtual Time ScoreProcessing::TimeConverter::convertMBUToTime	(	int	measure,
		int	beat,
		int	unit_num,
		int	unit_denom
	)			[pure virtual]

Convert a musical time expressed in Measure, Beat, Unit format into a value expressed in whole note (1/4 means a quarter note). This time format is typically used for the score annotations.

Parameters:

	measure	: the measure value.
	beat	: the beat value.
	unit_num	: the unit value numerator.
	unit_denom	: the unit value denominator.

Returns:

The musical time expressed in whole note.

virtual void ScoreProcessing::TimeConverter::convertRolledToUnrolled	(	Time	rolled,
		std::vector< Time > &	unrolled
	)			[pure virtual]

Convert a rolled musical time position into a vector of the corresponding unrolled musical time positions in the score.

Parameters:

	rolled	: the rolled position expressed in whole note (1/4 means a quarter note).
	unrolled	: the vector to be filled with the unrolled musical time positions in the score.

virtual void ScoreProcessing::TimeConverter::convertTimeToMBU	(	Time	time_val,
		int &	measure,
		int &	beat,
		int &	unit_num,
		int &	unit_denom
	)			[pure virtual]

Convert a musical time expressed in whole note in a musical time expressed in Measure, Beat, Unit format. This time format is typically used for the score annotations.

Parameters:

	time_val	: the time in whole note to be converted.
	measure	: the measure value result.
	beat	: the beat value result.
	unit_num	: the unit value numerator result.
	unit_denom	: the unit value denominator result.

virtual Time ScoreProcessing::TimeConverter::convertUnrolledToRolled

(

Time

unrolled

)

[pure virtual]

Convert an unrolled musical time position into the corresponding rolled musical time position in the score.

Parameters:

unrolled

: the unrolled position expressed in whole note (1/4 means a quarter note).

Returns:

The rolled musical time position in the score.

static STimeConverter ScoreProcessing::TimeConverter::newTimeConverter

(

MusicXML::SScore

score

)

[static]

Allocates a new TimeConverter object.

Parameters:

score

the associated music score.

Returns:
