Class NamespaceCodeIterator

  • All Implemented Interfaces:
    IntIterator
    public class NamespaceCodeIterator
extends java.lang.Object
implements IntIterator
    This class provides an iterator over the namespace codes representing the in-scope namespaces of any node. It relies on nodes to implement the method NodeInfo.getDeclaredNamespaces(int[]).

    The result does not include the XML namespace.

    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      boolean hasNext()
      Test whether there are any more integers in the sequence
      static IntIterator iterateNamespaces​(NodeInfo element)
      Factory method: create an iterator over the in-scope namespace codes for an element
      int next()
      Return the next integer in the sequence.
      static void sendNamespaces​(NodeInfo element, Receiver receiver)
      Send all the in-scope namespaces for a node to a specified receiver

      • iterateNamespaces

        public static IntIterator iterateNamespaces​(NodeInfo element)
        Factory method: create an iterator over the in-scope namespace codes for an element
        Parameters:
        element - the element (or other node) whose in-scope namespaces are required. If this is not an element, the result will be an empty iterator
        Returns:
        an iterator over the namespace codes. A namespace code is an integer that represents a prefix-uri binding; the prefix and URI can be obtained by reference to the name pool. This iterator will represent all the in-scope namespaces, without duplicates, and respecting namespace undeclarations. It does not include the XML namespace.

      • sendNamespaces

        public static void sendNamespaces​(NodeInfo element,
                                  Receiver receiver)
                           throws XPathException
        Send all the in-scope namespaces for a node to a specified receiver
        Parameters:
        element - the element in question (the method does nothing if this is not an element)
        receiver - the receiver to which the namespaces are notified
        Throws:
        XPathException

      • hasNext

        public boolean hasNext()
        Description copied from interface: IntIterator
        Test whether there are any more integers in the sequence
        Specified by:
        hasNext in interface IntIterator
        Returns:
        true if there are more integers to come

      • next

        public int next()
        Description copied from interface: IntIterator
        Return the next integer in the sequence. The result is undefined unless hasNext() has been called and has returned true.
        Specified by:
        next in interface IntIterator
        Returns:
        the next integer in the sequence
