Member Function Documentation

CACrescendo * CACrescendo::clone ( CAMusElement * elt = 0 ) [virtual]

Reimplemented from CAMark.

References CACrescendo(), crescendoType(), finalVolume(), CAMusElement::musElementType(), CAMusElement::Note, CAMusElement::timeLength(), and CAMusElement::timeStart().

Here is the call graph for this function:

int CACrescendo::compare ( CAMusElement * elt ) [virtual]

Compares the music element with the given elt and returns number of differences in their properties. Returns 0, if the music elements are exact; -1 if the music element type differs; otherwise number greater than 0.

This method is usually used when opening a score document where music elements are written in various voices (eg. barlines), but are eventually merged and written only once per staff.

Reimplemented from CAMark.
