Count the number of commits that are reachable from start until a commit that is reachable from end is encountered. In other words, count the number of commits that are in start, but not in end.

Parameters:

walk - the rev walk to use

start - the commit to start counting from

end - the commit where counting should end, or null if counting should be done until there are no more commits

Returns:

the number of commits

Throws:

MissingObjectException
