Interface XLongIterator

All Known Subinterfaces:

XLongListIterator

All Known Implementing Classes:

XLongArrayIterator

public interface XLongIterator

This interface represents an iterator for primitive long values. Its semantics are the same as those for Iterator

Method Summary

Methods

Modifier and Type	Method and Description
boolean	hasNext() Returns true if the iteration has more elements.
long	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by the iterator (optional operation).
XLongIterator	toFirst() Resets the iterator to the beginning.

Method Detail

hasNext

boolean hasNext()

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Returns:

true if the iterator has more elements.

next

long next()

Returns the next element in the iteration.

Returns:

the next element in the iteration.

Throws:

NoSuchElementException - iteration has no more elements.

remove

void remove()

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Throws:

UnsupportedOperationException - if the remove operation is not supported by this Iterator.

IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

toFirst

XLongIterator toFirst()

Resets the iterator to the beginning.

Throws:

UnsupportedOperationException - if the toFirst operation is not supported by this iterator.
