Field Detail

EMPTY_ITERATOR

public static final ArrayRangeIterator EMPTY_ITERATOR

Empty iterator used whenever possible.

m_array

protected Object[] m_array

Array supplying values for iteration.

m_offset

protected int m_offset

Offset of next iteration value.

m_limit

protected int m_limit

Ending offset for values.

Method Detail

hasNext

public boolean hasNext()

Check for iteration element available.

Specified by:

hasNext in interface Iterator

Returns:

true if element available, false if not

next

public Object next()

Get next iteration element.

Specified by:

next in interface Iterator

remove

public void remove()

Remove element from iteration. This optional operation is not supported and always throws an exception.

Specified by:

remove in interface Iterator

Throws:

UnsupportedOperationException - for unsupported operation

buildIterator

public static Iterator buildIterator(Object[] array,
                                     int start,
                                     int limit)

Build iterator.

Parameters:

array - array containing values to be iterated (may be null)

start - starting offset in array

limit - offset past end of values

Returns:

constructed iterator
