Method Detail

of

static <T> Stream<List<T>> of(Collection<T> collection)

Method to get the Stream of permutations.

Type Parameters:

T - The Collection element type.

Parameters:

collection - The Collection of elements to permute.

Returns:

The Stream of permutations.

of

static <T> Stream<List<T>> of(Predicate<List<T>> predicate,
                              Collection<T> collection)

Method to get the Stream of permutations.

Type Parameters:

T - The Collection element type.

Parameters:

predicate - The optional Predicate (may be null) specifying prerequisite requirement(s) for the combinations. Any path that does not match will be pruned.

collection - The Collection of elements to permute.

Returns:

The Stream of permutations.
