Class PrependIterator
java.lang.Object
net.sf.saxon.om.PrependIterator
- All Implemented Interfaces:
AxisIterator
,SequenceIterator
An iterator over nodes, that prepends a given node to the nodes
returned by another iterator. Used to modify an iterator over axis A
to one that iterates over A-OR-SELF.

Method Details
-
next
Get the next item in the sequence.- Specified by:
next
in interfaceAxisIterator
- Specified by:
next
in interfaceSequenceIterator
- Returns:
- the next Item. If there are no more nodes, return null.
-
current
Get the current item in the sequence.- Specified by:
current
in interfaceAxisIterator
- Specified by:
current
in interfaceSequenceIterator
- Returns:
- the current item, that is, the item most recently returned by next()
-
position
public int position()Get the current position- Specified by:
position
in interfaceAxisIterator
- Specified by:
position
in interfaceSequenceIterator
- Returns:
- the position of the current item (the item most recently returned by next()), starting at 1 for the first node
-
getAnother
Get another iterator over the same sequence of items, positioned at the start of the sequence- Specified by:
getAnother
in interfaceAxisIterator
- Specified by:
getAnother
in interfaceSequenceIterator
- Returns:
- a new iterator over the same sequence
-
getProperties
public int getProperties()Get properties of this iterator, as a bit-significant integer.- Specified by:
getProperties
in interfaceSequenceIterator
- Returns:
- the properties of this iterator. This will be some combination of
properties such as
SequenceIterator.GROUNDED
,SequenceIterator.LAST_POSITION_FINDER
, andSequenceIterator.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.
