Class NamespaceIterator

java.lang.Object
net.sf.saxon.om.NamespaceIterator
All Implemented Interfaces:
AxisIterator, SequenceIterator

public class NamespaceIterator extends 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 method NodeInfo.getDeclaredNamespaces(int[])

  • Method Details

    • 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 interface AxisIterator
      Specified by:
      next in interface SequenceIterator
      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 interface AxisIterator
      Specified by:
      current in interface SequenceIterator
      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 interface AxisIterator
      Specified by:
      position in interface SequenceIterator
      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 interface AxisIterator
      Specified by:
      getAnother in interface SequenceIterator
      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 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.
    • 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.
