Constructor Detail

ConcatenatingIntIterator

public ConcatenatingIntIterator(IntIterator first,
                                java.util.function.Supplier<IntIterator> second)

Create an iterator that concatenates the results of two supplied iterator. The second iterator isn't created until it is actually needed.

Parameters:

first - the first iterator

second - a function that can be called to supply the second iterator

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: IntIterator

Test whether there are any more integers in the sequence; and change the state of the iterator so a call on IntIterator.next() delivers the next integer.

The effect of calling #hasNext() a second time without an intervening call on #next() is undefined.

Specified by:

hasNext in interface IntIterator

Returns:

true if there are more integers to come

next

public int next()

Get the next item in the sequence.

Specified by:

next in interface IntIterator

Returns:

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