    - #### XSNamedMap4Types

          public XSNamedMap4Types(java.lang.String namespace,
                                  SymbolHash map,
                                  short type)

      Construct an XSNamedMap implementation for one namespace
      Parameters:
        `namespace` - the namespace to which the components belong
        `map` - the map from local names to components
        `type` - the type of components

    - #### XSNamedMap4Types

          public XSNamedMap4Types(java.lang.String[] namespaces,
                                  SymbolHash[] maps,
                                  int num,
                                  short type)

      Construct an XSNamedMap implementation for a list of namespaces
      Parameters:
        `namespaces` - the namespaces to which the components belong
        `maps` - the maps from local names to components
        `num` - the number of namespaces
        `type` - the type of components

  - ### Method Detail

    - #### getLength

          public int getLength()

      The number of `XSObjects` in the `XSObjectList`. The range of valid child node indices is 0 to `length-1` inclusive.
      Specified by:
        `getLength` in interface `org.apache.xerces.xs.XSNamedMap`
      Overrides:
        `getLength` in class `XSNamedMapImpl`

    - #### itemByName

          public org.apache.xerces.xs.XSObject itemByName(java.lang.String namespace,
                                                          java.lang.String localName)

      Retrieves an `XSObject` specified by local name and namespace URI.
      Specified by:
        `itemByName` in interface `org.apache.xerces.xs.XSNamedMap`
      Overrides:
        `itemByName` in class `XSNamedMapImpl`
      Parameters:
        `namespace` - The namespace URI of the `XSObject` to retrieve.
        `localName` - The local name of the `XSObject` to retrieve.
      Returns:
        A `XSObject` (of any type) with the specified local name and namespace URI, or `null` if they do not identify any `XSObject` in this map.

    - #### item

          public org.apache.xerces.xs.XSObject item(int index)

      Returns the `index`th item in the map. The index starts at 0. If `index` is greater than or equal to the number of nodes in the list, this returns `null`.
      Specified by:
        `item` in interface `org.apache.xerces.xs.XSNamedMap`
      Overrides:
        `item` in class `XSNamedMapImpl`
      Parameters:
        `index` - The position in the map from which the item is to be retrieved.
      Returns:
        The `XSObject` at the `index`th position in the `XSNamedMap`, or `null` if that is not a valid index.
