I'm thinking of cases where such a convenience methods could rely on
more than just a single property. For example, a getNumberOfPages()
convenience method could look something like this (with an extra
getInt(String) helper method):
int getNumberOfPages() {
Integer pages = metadata.getInt(PagedText.N_PAGES);
if (pages == null) {
pages = metadata.getInt(MSOffice.PAGE_COUNT);
}
if (pages == null) {
pages = metadata.getInt(MSOffice.SLIDE_COUNT);
}
if (pages != null) {
return pages;
} else {
return 0;
}
}
