Method Detail

concat

default IEnumerable<T> concat(Iterable<? extends T> second)

Creates a composite enumerable that enumerates two given iterables one after the other.

Parameters:

second - The second one.

Returns:

An IEnumerable which enumerate of the first iterable and then over the second.

concat

static <T> IEnumerable<T> concat(Iterable<? extends T> first,
                                 Iterable<? extends T> second)

Creates a composite enumerable that enumerates two given iterables one after the other.

Parameters:

first - The first one.

second - The second one.

Returns:

An IEnumerable which enumerate of the first iterable and then over the second.

create

static <T> IEnumerable<T> create(Iterable<T> iterable)

Returns an IEnumerable wrapping the specified Iterable.

Type Parameters:

T - The type of the elements returned by the Iterable.

Parameters:

iterable - The iterable to wrap.

Returns:

an IEnumerable wrapping the specified Iterable.

create

static <T> IEnumerable<T> create(T value)

Type Parameters:

T - The type of elements returned by the enumerator.

Parameters:

value - The item to enumerate.

Returns:

enumerable that enumerates a single item.

enumerator

IEnumerator<T> enumerator()

Returns an IEnumerator over a set of elements of type T.

Returns:

an IEnumerator.

iterator

default Iterator<T> iterator()

Specified by:

iterator in interface Iterable<T>

parallelStream

default Stream<T> parallelStream()

Returns a parallel Stream using the elements of this enumerable.

Returns:

a parallel Stream using the elements of this enumerable.

stream

default Stream<T> stream()

Returns a sequential Stream using the elements of this enumerable.

Returns:

a sequential Stream using the elements of this enumerable.
