Class Factory mapping Rule Combining Algorithm identifiers to their class implementations

Instance Methods

[hide private]

__init__(self, map={'urn:oasis:names:tc:xacml:1.0:policy-combining-algorithm:deny...)
Initialise mapping of identifiers to class implementations source code

RuleCombiningAlgInterface derived type or NoneType if no match is found or NotImplementedType if the identifier corresponds to a valid XACML rule combining algorithm but is not supported in this implementation

__call__(self, identifier)
Return the class for a given Rule Combining Algorithm identifier

init(self, map=`{'urn:oasis:names:tc:xacml:1.0:policy-combining-algorithm:deny...`)
(Constructor)

source code

Initialise mapping of identifiers to class implementations

Parameters:

map - mapping of rule combining algorithms IDs to classes. Set this to override the default taken from the DEFAULT_MAP class variable

Overrides: object.__init__

call(self, identifier)
(Call operator)

source code

Return the class for a given Rule Combining Algorithm identifier

Parameters:

identifier (basestring) - XACML rule combining algorithm urn

Returns: RuleCombiningAlgInterface derived type or NoneType if no match is found or NotImplementedType if the identifier corresponds to a valid XACML rule combining algorithm but is not supported in this implementation

rule combining class corresponding to the given input identifier
