- All Implemented Interfaces:
AxisIterator
,SequenceIterator
public class NamespaceIterator extends java.lang.Object implements AxisIterator
This class provides an implementation of the namespace axis over any implementation of the data model. It relies on element nodes to implement the methodNodeInfo.getDeclaredNamespaces(int[])

Method Detail
-
advance
public void advance()
Get the next item in the sequence.
-
next
public Item 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
public Item 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
public SequenceIterator 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.
-
getInScopeNamespaceCodes
public int[] getInScopeNamespaceCodes()
Get a list of in-scope namespace codes. If an array of namespace codes is needed, without actually constructing the namespace nodes, a caller may create the NamespaceIterator and then call this method. The result is an array of integers, each containing a prefix code in the top half and a uri code in the bottom half. Note that calling this method is destructive: the iterator is consumed and cannot be used again.
