Method Detail

compare

public 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 all x and y.

The implementor must ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Furthermore, the implementer must ensure that compare(x, y)==0 implies that sgn(compare(x, z))==sgn(compare(y, z)) for all z.

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.
