Constructor Details

IndexIterator

public IndexIterator(SequenceIterator base,
                     AtomicValue value,
                     GenericAtomicComparer comparer)
Get an iterator returning the index positions of selected items in a sequence
Parameters:
base - The sequence to be searched
value - The value being sought
comparer - Comparer used to determine whether values match

Method Details

current

public Item current()
Specified by:
current in interface SequenceIterator

getAnother

public SequenceIterator getAnother()
            throws XPathException
Specified by:
getAnother in interface SequenceIterator

getProperties

public int getProperties()
Get properties of this iterator, as a bit-significant integer.
Specified by:
getProperties in interface SequenceIterator
Returns:
the properties of this iterator. This will be some combination of properties such as SequenceIterator.GROUNDED, SequenceIterator.LAST_POSITION_FINDER, and SequenceIterator.LOOKAHEAD. It is always acceptable to return the value zero, indicating that there are no known special properties. It is acceptable for the properties of the iterator to change depending on its state.

next

public Item next()
            throws XPathException
Specified by:
next in interface SequenceIterator

position

public int position()
Specified by:
position in interface SequenceIterator
