static Ordering<java.lang.Object> |
Ordering.allEqual() |
Returns an ordering which treats all values as equal, indicating "no
ordering." Passing this ordering to any stable sort algorithm
results in no change to the order of elements.
|
static Ordering<java.lang.Object> |
Ordering.arbitrary() |
Returns an arbitrary ordering over all objects, for which compare(a,
b) == 0 implies a == b (identity equality).
|
static <T> Ordering<T> |
Ordering.compound(java.lang.Iterable<? extends java.util.Comparator<? super T>> comparators) |
Returns an ordering which tries each given comparator in order until a
non-zero result is found, returning that result, and returning zero only if
all comparators return zero.
|
<U extends T> Ordering<U> |
Ordering.compound(java.util.Comparator<? super U> secondaryComparator) |
Returns an ordering which first uses the ordering this , but which
in the event of a "tie", then delegates to secondaryComparator .
|
static <T> Ordering<T> |
Ordering.explicit(java.util.List<T> valuesInOrder) |
Returns an ordering that compares objects according to the order in
which they appear in the given list.
|
static <T> Ordering<T> |
Ordering.explicit(T leastValue,
T... remainingValuesInOrder) |
Returns an ordering that compares objects according to the order in
which they are given to this method.
|
static <T> Ordering<T> |
Ordering.from(Ordering<T> ordering) |
Deprecated.
|
static <T> Ordering<T> |
Ordering.from(java.util.Comparator<T> comparator) |
Returns an ordering based on an existing comparator instance.
|
<S extends T> Ordering<java.lang.Iterable<S>> |
Ordering.lexicographical() |
Returns a new ordering which sorts iterables by comparing corresponding
elements pairwise until a nonzero result is found; imposes "dictionary
order".
|
static <C extends java.lang.Comparable> Ordering<C> |
Ordering.natural() |
Returns a serializable ordering that uses the natural order of the values.
|
<S extends T> Ordering<S> |
Ordering.nullsFirst() |
Returns an ordering that treats null as less than all other values
and uses this to compare non-null values.
|
<S extends T> Ordering<S> |
Ordering.nullsLast() |
Returns an ordering that treats null as greater than all other
values and uses this ordering to compare non-null values.
|
<F> Ordering<F> |
Ordering.onResultOf(Function<F,? extends T> function) |
Returns a new ordering on F which orders elements by first applying
a function to them, then comparing those results using this .
|
<S extends T> Ordering<S> |
Ordering.reverse() |
Returns the reverse of this ordering; the Ordering equivalent to
Collections.reverseOrder(Comparator) .
|
static Ordering<java.lang.Object> |
Ordering.usingToString() |
Returns an ordering that compares objects by the natural ordering of their
string representations as returned by toString() .
