[jsword-devel] Passage constructors

[DM Smith]

The Passage hierarchy has not allowed the creation of Passage objects except through a factory method that constructs all Passages according to a chosen default.

The exception was a TallyPassage, which was used by JSword's index search to create prioritized hit lists.

I've changed the default constructors to be public. These create an empty Passage of a given versification.

This now make it possible for a program that controls input to optimize passage construction for time/space.

The other constructors that take a string that needs to be parsed are still all protected. However, you can use the following to cast from one type of passage to another.

Key k = ...; This can be a Passage, VerseRange or Verse.
Passage p = RangedPassage(v11n);
p.addAll(k);

If you create a Verse or a VerseRange, you can add it to RangedPassage with add(k) rather than addAll(k).

In Him,
