Method Details

[hide private]

init(self, arguments=None, **args)
(Constructor)

source code

Construct a new 'Extension'.

'args': Keyword arguments providing values for Extension parameters. The values should be appropriate for the corresponding fields. Derived classes must pass along any unrecognized keyword arguments to this method so that additional arguments can be added in the future without necessitating changes to derived classes.

This method will place all of the arguments into this objects instance dictionary.

Derived classes may override this method, but should call this method during their processing.

Overrides: object.__init__: (inherited documentation)

Class Variable Details

[hide private]

arguments

A list of the arguments to the extension class.

Each element of this list should be an instance of 'Field'. The 'Field' instance describes the argument.

Derived classes may redefine this class variable. However, derived classes should not explicitly include the arguments from base classes; QMTest will automatically combine all the arguments found throughout the class hierarchy.

Value:

[<<class 'qm.fields.TextField'> db_name>,
 <<class 'qm.fields.TextField'> db_module>,
 <<class 'qm.fields.PythonField'> connection>]

_argument_dictionary

A map from argument names to 'Field' instances.

A map from the names of arguments for this class to the corresponding 'Field'.

Value:

{'connection': <<class 'qm.fields.PythonField'> connection>,
 'db_module': <<class 'qm.fields.TextField'> db_module>,
 'db_name': <<class 'qm.fields.TextField'> db_name>}

_argument_list

A list of all the 'Field's in this class.

This list combines the complete list of 'arguments'. 'Field's appear in the order reached by a pre-order breadth-first traversal of the hierarchy, starting from the most derived class.

Value:

[<<class 'qm.fields.TextField'> db_module>,
 <<class 'qm.fields.PythonField'> connection>,
 <<class 'qm.fields.TextField'> db_name>]
