public ListOfOnixElement()

Method Details

values

public List<V> values()

returns a list of the values stored within the elements of this list (as opposed to the elements themselves, each of which also contains attributes, which are usually not interesting)

Returns:

a non-null, possibly empty, list of the values

valuesInto

public <C extends Collection<V>> C valuesInto(C collection)

stores into a given Collection the values stored within the elements of this list (as opposed to the elements themselves, each of which also contains attributes, which are usually not interesting)

Returns:

the same passed collection, after being populated

first

public Optional<E> first()

Returns:

an Optional of the first OnixElement listed, if any. Since OnixElement contains a value and some (less-interesting) attributes, a more typical API is firstValue().

firstValue

public Optional<V> firstValue()

Returns:

an Optional of the value in the first OnixElement listed, if any

firstValueOrNull

public V firstValueOrNull()

Returns:

the value in the first OnixElement listed, or null it the none is listed

empty

public static <X extends OnixElement<Y>,
Y>
ListOfOnixElement<X,Y> empty()
