Method Detail

extractTypeNames

protected static QName[] extractTypeNames(Map<String,String> kvpParam,
                                          Map<String,String> nsBindings)
                                   throws InvalidParameterValueException

Extracts the qualified type names from the TYPENAME parameter.

Parameters:

kvpParam - the parameters of the request, normalized

nsBindings - namespace bindings, may be null

Returns:

qualified type names or null if no TYPENAME parameter is present

Throws:

InvalidParameterValueException - if the value of the TYPENAME attribute contains a syntactical error or uses unbound prefices

qualifyName

protected static QName qualifyName(String name,
                                   Map<String,String> nsBindings)

Transforms a (possibly prefixed) type name into a qualified name using the given namespace bindings.

Parameters:

name - possibly prefixed type name

nsBindings - namespace bindings, may be null

Returns:

qualified name

extractNamespaceBindings

protected static Map<String,String> extractNamespaceBindings(Map<String,String> kvpUC)
                                                      throws InvalidParameterValueException

Extracts the namespace bindings from the NAMESPACE parameter.

• NAMESPACE=xmlns(myns=http://www.someserver.com),xmlns(yourns=http://www.someotherserver.com)

The default namespace may also be bound (two variants are supported):

• NAMESPACE=xmlns(=http://www.someserver.com)
• NAMESPACE=xmlns(http://www.someserver.com)

Parameters:

kvpUC - the parameters of the request, normalized

Returns:

mapping between prefices and namespaces (key: prefix, value: namespace), empty string as a key ('') is the binding of the default namespace, null is returned if no NAMESPACE parameter is present

Throws:

InvalidParameterValueException - if the value of the NAMESPACE attribute contains a syntactical error
