Method Details [hide private]

__call__(self, obj, common)
(Call operator)

source code 

Parse *AttributeValue type element - override this method instead of _parseExtension since AttributeValue class is virtual. A sub-type can be instantiated only once the data type attribute is parsed

Parameters:
  • obj (ElementTree Element, or stream object) - input object to parse
Returns: ndg.xacml.core.attributevalue.AttributeValue derived type
new XACML attribute value instance
Raises:
Overrides: AbstractReader.__call__

_parseExtension(self, elem, attributeValue)

source code 

Parse XML Attribute value element

Parameters:
  • elem (xml.etree.Element) - ElementTree XML element
  • attributeValue (ndg.xacml.core.attributevalue.AttributeValue) - attribute selector to be updated with parsed values
Raises:
Overrides: expressionreader.ExpressionReader._parseExtension
