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 java.util.NoSuchElementException

Delegated to the underlying iterator.

Specified by:

skip in interface RangeIterator

Parameters:

n - number of elements to skip

Throws:

java.util.NoSuchElementException - if skipped past the last element

hasNext

public boolean hasNext()

Delegated to the underlying iterator.

Specified by:

hasNext in interface java.util.Iterator

Returns:

true if the iterator has more elements, false otherwise

next

public java.lang.Object next()
                      throws java.util.NoSuchElementException

Delegated to the underlying iterator.

Specified by:

next in interface java.util.Iterator

Returns:

next element

Throws:

java.util.NoSuchElementException - if there are no more elements

remove

public void remove()
            throws java.lang.UnsupportedOperationException,
                   java.lang.IllegalStateException

Delegated to the underlying iterator.

Specified by:

remove in interface java.util.Iterator

Throws:

java.lang.UnsupportedOperationException - if the operation is not supported

java.lang.IllegalStateException - if there is no element to be removed
