Method Details

[hide private]

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

source code

Parse policy object

Parameters:

obj (ElementTree Element, or stream object) - input object to parse
common (from ndg.xacml.parsers.common.Common) - parsing common data

Returns: ndg.xacml.core.policy.Policy derived type

new XACML expression instance

Raises:

XMLParseError - error reading element
NotImplementedError - parsing is not implemented for rule combiner, combiner parameters and obligations elements.

Overrides: AbstractReader.__call__

parse(cls, obj, common=None)
Class Method

source code

Parse from input object and return new XACML object As a special case, allow the common data to be None. This is because for parsing a policy rather than a policy set, no common data is needed.

Parameters:

obj (string, stream or other) - input source - file name, stream object or other
common (from ndg.xacml.parsers.common.Common) - parsing common data

Returns: XacmlCoreBase sub type

new XACML object

Overrides: AbstractReader.parse

processElement(self, elem, common)

source code

Parse policy object

Parameters:

elem (ElementTree Element) - root element of policy
common (from ndg.xacml.parsers.common.Common) - parsing common data

Returns: ndg.xacml.core.policy.Policy derived type

new XACML expression instance

Raises:

XMLParseError - error reading element
NotImplementedError - parsing is not implemented for rule combiner, combiner parameters and obligations elements.
