Method Detail

wrap

public static IntIterator wrap(java.util.Iterator iterator)
Create an IntIterator wrapping the specified Iterator. When the given iterator is null, returns null.

Parameters:
iterator - the (possibly null) Iterator to wrap
Returns:
an IntIterator wrapping the given iterator, or null when iterator is null.

hasNext

public boolean hasNext()
Description copied from interface: IntIterator
Returns true iff I have more elements. (In other words, returns true iff a subsequent call to next will return an element rather than throwing an exception.)

Specified by:
hasNext in interface IntIterator
Returns:
true iff I have more elements

next

public int next()
Description copied from interface: IntIterator
Returns the next element in me.

Specified by:
next in interface IntIterator
Returns:
the next element in me

remove

public void remove()
Description copied from interface: IntIterator
Removes from my underlying collection the last element returned by me (optional operation).

Specified by:
