Constructor Details

XSNamedMapImpl

public XSNamedMapImpl(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(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(org.apache.xerces.xs.XSObject array,
                      int length)
Construct an XSNamedMap implmentation one namespace from an array

Parameters:
array - containing all components
length - number of components

Method Details

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


item

public org.apache.xerces.xs.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 org.apache.xerces.xs.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.


itemByName

public org.apache.xerces.xs.XSObject itemByName(String namespace,
                                                String localName)
Retrieves an XSObject specified by local name and namespace URI.
Specified by:
itemByName in interface org.apache.xerces.xs.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.
