Method Details

createOrderedEnumerable

<TKey> OrderedEnumerable<T> createOrderedEnumerable(Function1<T,TKey> keySelector,
 Comparator<TKey> comparator,
 boolean descending)

Performs a subsequent ordering of the elements in an OrderedEnumerable according to a key, using a specified comparator.

The functionality provided by this method is like that provided by thenBy or thenByDescending, depending on whether descending is true or false. They both perform a subordinate ordering of an already sorted sequence of type OrderedEnumerable.

thenBy

<TKey extends Comparable<TKey>>
OrderedEnumerable<T> thenBy(Function1<T,TKey> keySelector)

Performs a subsequent ordering of the elements in a sequence in ascending order according to a key.

thenBy

<TKey> OrderedEnumerable<T> thenBy(Function1<T,TKey> keySelector,
 Comparator<TKey> comparator)

Performs a subsequent ordering of the elements in a sequence in ascending order according to a key, using a specified comparator.

thenByDescending

<TKey extends Comparable<TKey>>
OrderedEnumerable<T> thenByDescending(Function1<T,TKey> keySelector)

Performs a subsequent ordering of the elements in a sequence in descending order according to a key.

thenByDescending

<TKey> OrderedEnumerable<T> thenByDescending(Function1<T,TKey> keySelector,
 Comparator<TKey> comparator)

Performs a subsequent ordering of the elements in a sequence in descending order according to a key, using a specified comparator.
