Interface NamedAccessNavigator

All Superinterfaces:
Navigator, Serializable
All Known Implementing Classes:

public interface NamedAccessNavigator extends Navigator
Interface for navigating around an arbitrary object model accessing certain parts by name for performance.

This interface must only be implemented by those models that can support this named access behavior.

  • Method Details

    • getChildAxisIterator

      Iterator getChildAxisIterator(Object contextNode, String localName, String namespacePrefix, String namespaceURI) throws UnsupportedAxisException
      Retrieve an Iterator that returns the child XPath axis where the names of the children match the supplied name and optional namespace.

      This method must only return element nodes with the correct name.

      If the namespaceURI is null, no namespace should be used. The prefix will never be null.

      Parameters:
      contextNode - the origin context node
      localName - the local name of the children to return, always present
      namespacePrefix - the prefix of the namespace of the children to return
      namespaceURI - the namespace URI of the children to return
      Returns:
      an Iterator capable of traversing the named children, or null if none
      Throws:
      UnsupportedAxisException - if the child axis is not supported by this object model
    • getAttributeAxisIterator

      Iterator getAttributeAxisIterator(Object contextNode, String localName, String namespacePrefix, String namespaceURI) throws UnsupportedAxisException
      Retrieve an Iterator that returns the attribute XPath axis where the names of the attributes match the supplied name and optional namespace.

      This method must only return attribute nodes with the correct name.

      If the namespaceURI is null, no namespace should be used. The prefix will never be null.

      Parameters:
      contextNode - the origin context node
      localName - the local name of the attributes to return, always present
      namespacePrefix - the prefix of the namespace of the attributes to return
      namespaceURI - the URI of the namespace of the attributes to return
      Returns:
      an Iterator capable of traversing the named attributes, or null if none
      Throws:
      UnsupportedAxisException - if the attribute axis is not supported by this object model
