Class SavedNamespaceContext

java.lang.Object
net.sf.saxon.instruct.SavedNamespaceContext
All Implemented Interfaces:
Serializable, NamespaceResolver

public final class SavedNamespaceContext extends Object implements 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.

      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.
