- Serializable, NamespaceResolver
public final class SavedNamespaceContext
extends java.lang.Object
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 context of a name pool
int[] | getNamespaceCodes() - Get the list of in-scope namespaces held in this NamespaceContext
|
String | getURIForPrefix(String prefix, boolean useDefault) - Get the namespace URI corresponding to a given prefix.
|
Iterator | iteratePrefixes() - Get an iterator over all the prefixes declared in this namespace context.

SavedNamespaceContext
public SavedNamespaceContext(int[] nscodes,
NamePool pool)
Create a NamespaceContext object
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.pool
- the namepool
SavedNamespaceContext
public SavedNamespaceContext(NamespaceResolver resolver,
NamePool pool)
Create a SavedNamespaceContext that captures all the information in a given NamespaceResolver
resolver
- the NamespaceResolverpool
- the NamePool
getNamespaceCodes
public int[] getNamespaceCodes()
Get the list of in-scope namespaces held in this NamespaceContext
getURIForPrefix
public String getURIForPrefix(String prefix,
boolean useDefault)
Get the namespace URI corresponding to a given prefix. Return null
if the prefix is not in scope.
- getURIForPrefix in interface NamespaceResolver
prefix
- the namespace prefixuseDefault
- true if the default namespace is to be used when the
prefix is ""
- the uri for the namespace, or null if the prefix is not in scope
iteratePrefixes
public 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
- iteratePrefixes in interface NamespaceResolver
