This is an abstract role which provides an alternate constructor for creating
|
||
|
|
objects using parameters passed in from a configuration file. The actual
|
||
|
|
implementation of reading the configuration file is left to concrete subroles.
|
||
|
|
|
||
|
|
It declares an attribute configfile and a class method new_with_config, and
|
||
|
|
requires that concrete roles derived from it implement the class method
|
||
|
|
get_config_from_file.
|
||
|
|
|
||
|
|
Attributes specified directly as arguments to new_with_config supercede those
|
||
|
|
in the configfile.
