ActionPluginComparator
public ActionPluginComparator()
compare
public int compare(Object o1,
Object o2)
- Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first
argument 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. (This implies that compare(x, y) must throw an exception if and only if compare(y,
x) throws an exception.)
The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y,
z)>0)) implies compare(x, z)>0.
Finally, the implementer must ensure that compare(x, y)==0 implies that sgn(compare(x,
z))==sgn(compare(y, z)) for all z.
It is generally the case, but not strictly required that (compare(x, y)==0) == (x.equals(y)).
Generally speaking, any comparator that violates this condition should clearly indicate this fact. The recommended
language is "Note: this comparator imposes orderings that are inconsistent with equals."
- Specified by:
compare
in interface Comparator
- Parameters:
o1
- the first object to be compared.o2
- the second object to be compared.
- Returns:
- a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater
than the second.
- Throws:
ClassCastException
- if the arguments' types prevent them from being compared by this Comparator.
