                                                         java.util.ListIterator itM,
                                                         java.util.ListIterator itMTP,

                                                  throws GPFormatException

Create and return a regular SongMeasure from the current position of the iterators.

Parameters:

itM - an iterator over the measures collection. It must be pointing so that itM.next() returns the current measure, which will be marked as a repeatStart.

itMTP - an iterator over the measure-track pairs collection. It must be pointing so that itMTP.next() returns the first track of the current measure

tracks - The tracks definitions

Returns:

a new filled-out SongMeasure

Throws:

GP4AdaptorException

GPFormatException

makeSongMeasure

private static SongMeasure makeSongMeasure(Song song,
                                           java.util.ListIterator itM,
                                           java.util.ListIterator itMTP,
                                           java.util.List tracks)

Create and return a regular SongMeasure from the current position of the iterators.

Parameters:

itM - an iterator over the measures collection. It must be pointing so that itM.next() returns the current measure

itMTP - an iterator over the measure-track pairs collection. It must be pointing so that itMTP.next() returns the first track of the current measure

tracks - The tracks definitions

Returns:

a new filled-out SongMeasure

Throws:

GP4AdaptorException

calculateDuration

                                 throws GPFormatException

Look ahead at the next measure, build and determine a suitable SongPhrase to handle it.

Parameters:

itM - an iterator over the measures collection. It must be pointing so that itM.next() returns the current measure, which will be marked as a repeatStart.

tracks - The tracks definitions

Returns:

the next SongPhrase

Throws:

GPFormatException
