Method Detail

next

Item next()

Get the next item in the sequence.

Specified by:

next in interface SequenceIterator

Returns:

the next Item. If there are no more items, return null.

forEach

default void forEach(java.util.function.Consumer<? super Item> consumer)

Process all the items returned by the iterator, supplying them to a given Consumer. Note that this method throws no exceptions. This method consumes the iterator.

Parameters:

consumer - the function that is to consume each of the (remaining) items returned by the iterator

toList

default java.util.List<Item> toList()

Create a list containing all the items returned by the iterator. This method consumes the iterator.

Returns:

a list containing all the (remaining) items returned by the iterator
