int compare(RefactoringStatusEntry entry1, RefactoringStatusEntry entry2)
Compares two refactoring status entries for order. Returns a negative integer, zero, or a positive integer as the first status entry is less than, equal to, or greater than the second.The implementor must ensure that
sgn(compare(x, y)) == -sgn(compare(y, x))for allxandy.The implementor must ensure that the relation is transitive:
((compare(x, y)>0) && (compare(y, z)>0))impliescompare(x, z)>0.Furthermore, the implementer must ensure that
compare(x, y)==0implies thatsgn(compare(x, z))==sgn(compare(y, z))for allz.- Parameters:
entry1- the first refactoring status entry to be compared.entry2- the second refactoring status entry to be compared.- Returns:
- a negative integer, zero, or a positive integer as the first status entry is less than, equal to, or greater than the second.
