jgdv.decorators.mixin

Classes

`DelayMixin`	TODO A Decorator for annotating a class with mixins
`Mixin`	Decorator to App/Prepend Mixins into the decorated class.
`MixinNow`	TODO The trigger for delayed mixins.

class jgdv.decorators.mixin.DelayMixin(keys, **kwargs)[source]

TODO A Decorator for annotating a class with mixins

Delays the construction of the True class until later, using @MixinNow

class jgdv.decorators.mixin.Mixin( *mixins, allow_inheritance=False, silent=False, )[source]

Decorator to App/Prepend Mixins into the decorated class.

Converts:

class ClsName(mixins, Supers, Protocols, metaclass=MCls, **kwargs):...

into:

@Protocols(*ps)
@Mixin(*ms, None)
class ClsName(Supers): ...

(‘None’ is used to separate pre and post mixins)

Parameters:

_build_annotations_h(target, current) → <Unknown>[source]

Given a list of the current annotation list, return its replacement

Parameters:

Return type:

jgdv.Maybe[list]

_validate_mixins() → <Unknown>[source]

_validate_target_h( target, form, args=None, ) → <Unknown>[source]

Abstract class for specialization. Given the original target, throw an error here if it isn’t ‘correct’ in some way

Parameters:

Return type:

None

_wrap_class_h(cls) → <Unknown>[source]

Override this to decorate a class

class jgdv.decorators.mixin.MixinNow( *args, prefix=None, mark=None, data=None, )[source]

TODO The trigger for delayed mixins.

After using @DelayMixin, trigger the True class using this.

eg:

@MixinNow
@DelayMixin(m3, None, m4)
@DelayMixin(m1, m2)
class Blah:...

Parameters:
