Method Details [hide private]

__init__(self)
(Constructor)

source code 

Force entries to derive from AttributeValue and IDs to be string type

Parameters:
  • args - two arguments: the first is a callable which filters for permissable keys in this dict, the second sets the type or list of types permissable for items in this dict
Overrides: utils.VettedDict.__init__

keyFilter(key)
Static Method

source code 

Enforce string type keys for Attribute Value DataType URIs

Parameters:
  • key (basestring) - URN for attribute
Returns: bool
boolean True indicating key is OK
Raises:
  • TypeError - incorrect input type

valueFilter(value)
Static Method

source code 

Enforce ElementTree abstract reader derived types for values

Parameters:
  • value (ndg.xacml.parsers.etree.attributevaluereader.ETreeDataTypeReaderBase to their derived type) - attribute value
Returns: bool
boolean True indicating attribute value is correct type
Raises:
  • TypeError - incorrect input type
