Method Detail

wrap

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

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

hasNext

public boolean hasNext()
Description copied from interface: LongIterator
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 LongIterator
Returns:
true iff I have more elements

next

public long next()
Description copied from interface: LongIterator
Returns the next element in me.

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

remove

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

Specified by:
remove in interface LongIterator
