Interface NamespaceContext2
- All Superinterfaces:
NamespaceContext
- All Known Implementing Classes:
NamespaceContextImpl
Maintains
namespace <-> prefix
bindings.
This interface extends NamespaceContext
and provides
an additional functionality, which is necessary to declare
namespaced attributes on elements. The added method is for
self-consumption by the marshaller.
This object is composed into a Serializer.

declareNamespace
Declares a new namespace binding within the current context.The prefix is automatically assigned by MarshallingContext. If a given namespace URI is already declared, nothing happens.
It is NOT an error to declare the same namespace URI more than once.
For marshalling to work correctly, all namespace bindings for an element must be declared between its startElement method and its endAttributes event. Calling the same method with the same parameter between the endAttributes and the endElement returns the same prefix.
- Parameters:
requirePrefix
- If this parameter is true, this method must assign a prefix to this namespace, even if it's already bound to the default namespace. IOW, this method will never return null if this flag is true. This functionality is necessary to declare namespace URI used for attribute names.preferedPrefix
- If the caller has any particular preference to the prefix, pass that as a parameter. The callee will try to honor it. Set null if there's no particular preference.- Returns:
- returns the assigned prefix. If the namespace is bound to the default namespace, null is returned.
-
force
Forcibly make a namespace declaration in effect. If the (prefix,uri) binding is already in-scope, this method simply returns the assigned prefix index. Otherwise a new declaration will be put.
