Method Details

[hide private]

init(self, constructed_object)
(Constructor)

source code

Initialize a new Builder.

Concrete Builders should call this method from within their own __init__ method. The concrete __init__ method should also register all build options to build methods, by using the _register method.

Parameters:

constructed_object - An instance of an object this builder is responsible for.

build(self, build_option, **kwargs)

source code

Build a piece of the constructed object.

Parameters:

build_option (str) - The part of the object to build. All build options should have been registered in __init__.
kwargs - Additional arguments for building.

_register(self, build_option, build_method)

source code

All concrete builders should call this method in their constructor at least once.

Parameters:

build_option (str) - A string representing the part of the object to build.
build_method - The method to call when given build option is selected.
