      extended by org.apache.xerces.impl.xs.SchemaNamespaceSupport
All Implemented Interfaces:
org.apache.xerces.xni.NamespaceContext

public class SchemaNamespaceSupport
extends NamespaceSupport

This class customizes the behaviour of the util.NamespaceSupport class in order to easily implement some features that we need for efficient schema handling. It will not be generally useful.

Method Detail

setEffectiveContext

public void setEffectiveContext(java.lang.String[] namespaceDecls)
This method takes a set of Strings, as stored in a NamespaceSupport object, and "fools" the object into thinking that this is one unified context. This is meant to be used in conjunction with things like local elements, whose declarations may be deeply nested but which for all practical purposes may be regarded as being one level below the global element--at least with regard to namespace declarations. It's worth noting that the context from which the strings are being imported had better be using the same SymbolTable.


getEffectiveLocalContext

public java.lang.String[] getEffectiveLocalContext()
This method returns an array of Strings, as would be stored in a NamespaceSupport object. This array contains all declarations except those at the global level.


makeGlobal

public void makeGlobal()

getURI

public java.lang.String getURI(java.lang.String prefix)
Description copied from interface: org.apache.xerces.xni.NamespaceContext
Look up a prefix and get the currently-mapped Namespace URI.

This method looks up the prefix in the current context. If no mapping is found, this methods will continue lookup in the parent context(s). Use the empty string ("") for the default Namespace.

Specified by:
getURI in interface org.apache.xerces.xni.NamespaceContext
Overrides:
getURI in class NamespaceSupport
Parameters:
prefix - The prefix to look up.
Returns:
The associated Namespace URI, or null if the prefix is undeclared in this context.

NamespaceContext.getURI(String)
