Field Detail

EMPTY_MAP

public static final XSNamedMap EMPTY_MAP

An immutable empty map.

Constructor Detail

XSNamedMapImpl

public XSNamedMapImpl(java.lang.String namespace,
                      SymbolHash map)

Construct an XSNamedMap implmentation for one namespace

Parameters:

namespace - the namespace to which the components belong

map - the map from local names to components

XSNamedMapImpl

public XSNamedMapImpl(java.lang.String[] namespaces,
                      SymbolHash[] maps,
                      int num)

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

XSNamedMapImpl

public XSNamedMapImpl(XSObject[] array,
                      int length)

Construct an XSNamedMap implmentation one namespace from an array

Parameters:

array - containing all components

length - number 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 XSNamedMap

itemByName

public 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 XSNamedMap

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 XSObject item(int index)

Returns the indexth 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 XSNamedMap

Parameters:

index - The position in the map from which the item is to be retrieved.

Returns:

The XSObject at the indexth position in the XSNamedMap, or null if that is not a valid index.
