XSNamedMapImpl

• java.lang.Object

Fields Summary
public static final XSNamedMap	EMPTY_MAP An immutable empty map.
String[]	fNamespaces
int	fNSNum
SymbolHash[]	fMaps
XSObject[]	fArray
int	fLength
QName	fName

Constructors Summary
public XSNamedMapImpl(String namespace, SymbolHash map) Construct an XSNamedMap implmentation for one namespace param namespace the namespace to which the components belong param map the map from local names to components fNamespaces = new String[] {namespace}; fMaps = new SymbolHash[] {map}; fNSNum = 1;
public XSNamedMapImpl(String[] namespaces, SymbolHash[] maps, int num) Construct an XSNamedMap implmentation for a list of namespaces param namespaces the namespaces to which the components belong param maps the maps from local names to components param num the number of namespaces fNamespaces = namespaces; fMaps = maps; fNSNum = num;
public XSNamedMapImpl(XSObject[] array, int length) Construct an XSNamedMap implmentation one namespace from an array param array containing all components param length number of components if (length == 0) { fNSNum = 0; fLength = 0; return; } // because all components are from the same target namesapce, // get the namespace from the first one. fNamespaces = new String[]{array[0].getNamespace()}; fMaps = null; fNSNum = 1; // copy elements to the Vector fArray = array; fLength = length;

Methods Summary
public synchronized int	getLength() The number of XSObjects in the XSObjectList. The range of valid child node indices is 0 to length-1 inclusive. if (fLength == -1) { fLength = 0; for (int i = 0; i < fNSNum; i++) fLength += fMaps[i].getLength(); } return fLength;
public synchronized com.sun.org.apache.xerces.internal.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. param index The position in the map from which the item is to be retrieved. return The XSObject at the indexth position in the XSNamedMap, or null if that is not a valid index. if (fArray == null) { // calculate the total number of elements getLength(); fArray = new XSObject[fLength]; int pos = 0; // get components from all SymbolHash's for (int i = 0; i < fNSNum; i++) { pos += fMaps[i].getValues(fArray, pos); } } if (index < 0 || index >= fLength) return null; return fArray[index];
public com.sun.org.apache.xerces.internal.xs.XSObject	itemByName(java.lang.String namespace, java.lang.String localName) Retrieves an XSObject specified by local name and namespace URI. param namespace The namespace URI of the XSObject to retrieve. param localName The local name of the XSObject to retrieve. return 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. if (namespace != null) namespace = namespace.intern(); for (int i = 0; i < fNSNum; i++) { if (namespace == fNamespaces[i]) { // when this map is created from SymbolHash's // get the component from SymbolHash if (fMaps != null) return (XSObject)fMaps[i].get(localName); // Otherwise (it's created from an array) // go through the array to find a matcing name XSObject ret; for (int j = 0; j < fLength; j++) { ret = fArray[j]; if (ret.getName().equals(localName)) return ret; } return null; } } return null;
