  • Field Details

    • parent

      protected NamespaceContext parent
      The parent context, which may be null

    • namespaces

      protected Map namespaces
      map containing bound namespaces, keyed by their prefix. A LinkedHashMap is used to ensure that getPrefix(String) always returns the same prefix, unless that prefix is removed.

  • Constructor Details

    • SimpleNamespaceContext

      public SimpleNamespaceContext()
      Constructs a SimpleNamespaceContext with no parent context or namespace declarations.

    • SimpleNamespaceContext

      public SimpleNamespaceContext(Map namespaces)
      Constructs a SimpleNamespaceContext with no parent context that contains the specified prefixes.
      Parameters:
      namespaces - A Map of namespace URIs, keyed by their prefixes.

    • SimpleNamespaceContext

      public SimpleNamespaceContext(NamespaceContext parent)
      Constructs an empty SimpleNamespaceContext with the given parent. The parent context will be forwarded any requests for namespaces not declared in this context.
      Parameters:
      parent - The parent context.

    • SimpleNamespaceContext

      public SimpleNamespaceContext(NamespaceContext parent, Map namespaces)
      Constructs an empty SimpleNamespaceContext with the given parent. The parent context will be forwarded any requests for namespaces not declared in this context.
      Parameters:
      parent - The parent context.
      namespaces - A Map of namespace URIs, keyed by their prefixes.

  • Method Details

    • getParent

      public NamespaceContext getParent()
      Returns a reference to the parent of this context.
      Specified by:
      getParent in interface ExtendedNamespaceContext
      Returns:
      The parent context, or null if this is a root context.

    • setParent

      public void setParent(NamespaceContext parent)
      Sets the parent context used to inherit namespace bindings.
      Parameters:
      parent - The new parent context.

    • isRootContext

      public boolean isRootContext()
      Determines if this is a root context.
      Returns:
      true if this is a root context, false otherwise.

    • getNamespaceURI

      public String getNamespaceURI(String prefix)
      Specified by:
      getNamespaceURI in interface NamespaceContext

    • getPrefix

      public String getPrefix(String nsURI)
      Specified by:
      getPrefix in interface NamespaceContext

    • isPrefixDeclared

      public boolean isPrefixDeclared(String prefix)
      Determines if the specified prefix is declared within this context, irrespective of any ancestor contexts.
      Specified by:
      isPrefixDeclared in interface ExtendedNamespaceContext
      Parameters:
      prefix - The prefix to check.
      Returns:
      true if the prefix is declared in this context, false otherwise.

    • getDeclaredPrefixes

      public Iterator getDeclaredPrefixes()
      Description copied from interface: ExtendedNamespaceContext
      Returns an Iterator of all namespace prefixes declared within this context, irrespective of any ancestor contexts.
      Specified by:
      getDeclaredPrefixes in interface ExtendedNamespaceContext
      Returns:
      An Iterator of prefix Strings.

    • getDeclaredPrefixCount

      public int getDeclaredPrefixCount()
      Returns the number of namespace prefixes declared in this context.
      Returns:
      The number of namespace prefixes declared in this context.

    • getPrefixes

      public Iterator getPrefixes()
      Description copied from interface: ExtendedNamespaceContext

      Specified by:
      getPrefixes in interface ExtendedNamespaceContext
      Returns:
      An Iterator of prefix Strings.

    • getPrefixes

      public Iterator getPrefixes(String nsURI)
      Specified by:
      getPrefixes in interface NamespaceContext

    • setDefaultNamespace

      public String setDefaultNamespace(String nsURI)
