Interface XBooleanIterator

All Known Implementing Classes:

XBooleanArrayIterator

public interface XBooleanIterator

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

Method Summary

boolean	hasNext() Returns true if the iteration has more elements.
boolean	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by the iterator (optional operation).
XBooleanIterator	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

boolean 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

XBooleanIterator toFirst()

Resets the iterator to the beginning.

Throws:

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