Method Details [hide private]

__init__(self, value=None)
(Constructor)

source code 

Derived classes must override setting TYPE class variable

Parameters:
  • value ((set by self.__class__.TYPE)) - initialise the attribute value by setting this keyword
Raises:
  • NotImplementedError - derived classes must set ELEMENT_LOCAL_NAME to a string
Overrides: object.__init__

__repr__(self)
(Representation operator)

source code 

repr(x)

Overrides: object.__repr__
(inherited documentation)

_get_value(self)

source code 

Get value

Returns: any - constrained in derived classes
setting for this attribute value

_set_value(self, value)

source code 

Set value

Parameters:
  • value (any - constrained in derived classes) - setting for this attribute value
Raises:
  • TypeError - if type doesn't match TYPE class variable. Derived classes should set this

evaluate(self, context)

source code 

Evaluate the result of the expression in a condition. In the case of an attribute value it's simply itself

Parameters:
  • context (ndg.xacml.core.context.request.Request) - the request context
Returns: AttributeValue
this attribute value
Overrides: expression.Expression.evaluate

__getstate__(self)

source code 

Enable pickling

Returns: dict
object's attribute dictionary
Overrides: XacmlCoreBase.__getstate__
