Constructor Detail

### XSNamedMap4Types

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

  Construct an XSNamedMap implmentation 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 implmentation 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.
