CAMusElement * CALilyPondImport::findSharedElement ( CAMusElement * elt ) [private]

Gathers a list of music elements with the given element's start time and returns the first music element in the gathered list with the same attributes.

This method is usually called when voices have "shared" music elements (barlines, clefs etc.). However, in LilyPond syntax the music element can/should be present in all the voices. This function finds this shared music element, if it already exists.

If the music element with the same properties exists, user should delete its own instance and add an already existing instance of the returned shared music element to the voice.
