Constructor Detail

RangeIteratorDecorator

protected RangeIteratorDecorator(RangeIterator iterator)
Creates a decorated iterator. Protected since this class is only useful when subclassed.

Parameters:
iterator - the iterator to be decorated
Method Detail

getPosition

public long getPosition()
Delegated to the underlying iterator.

Specified by:
getPosition in interface RangeIterator
Returns:
iterator position

getSize

public long getSize()
Delegated to the underlying iterator.

Specified by:
getSize in interface RangeIterator
Returns:
iterator size

skip

public void skip(long n)
          throws NoSuchElementException
Delegated to the underlying iterator.

Specified by:
skip in interface RangeIterator
Parameters:
n - number of elements to skip
Throws:
NoSuchElementException - if skipped past the last element

hasNext

public boolean hasNext()
Delegated to the underlying iterator.

Specified by:
hasNext in interface Iterator
Returns:
true if the iterator has more elements, false otherwise

next

public Object next()
            throws NoSuchElementException
Delegated to the underlying iterator.

Specified by:
next in interface Iterator
Returns:
next element
Throws:
NoSuchElementException - if there are no more elements

remove

public void remove()
            throws UnsupportedOperationException,
                   IllegalStateException
