public final class SavedNamespaceContext extends java.lang.Object implements java.io.Serializable, NamespaceResolver
An object representing a list of Namespaces. Used when the namespace controller in the stylesheet needs to be kept for use at run-time. The list of namespaces is maintained in the form of numeric prefix/uri codes, which are only meaningful in the controller of a name pool; however, in order to save space, the NamespaceContext object does not keep a reference to the namepool, it requires this to be supplied by the caller.- See Also:

SavedNamespaceContext
public SavedNamespaceContext(int[] nscodes, NamePool pool)
Create a NamespaceContext object- Parameters:
nscodes
- an array of namespace codes. Each namespace code is an integer in which the first 16 bits represent the prefix (zero if it's the default namespace) and the next 16 bits represent the uri. These are codes held in the NamePool. The list will be searched from the "high" end.

getNamespaceCodes
public int[] getNamespaceCodes()
Get the list of in-scope namespaces held in this NamespaceContext- Returns:
- the list of namespaces
-
getURIForPrefix
public java.lang.String getURIForPrefix(java.lang.String prefix, boolean useDefault)
Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.- Specified by:
getURIForPrefix
in interfaceNamespaceResolver
- Parameters:
prefix
- the namespace prefixuseDefault
- true if the default namespace is to be used when the prefix is ""- Returns:
- the uri for the namespace, or null if the prefix is not in scope
-
iteratePrefixes
public java.util.Iterator iteratePrefixes()
Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate- Specified by:
iteratePrefixes
in interfaceNamespaceResolver
