brainprep.decorators.Hook

class brainprep.decorators.Hook

Bases: object

Base class for decorator hooks.

Hooks used with the decorator must inherit from this class and and optionally override before_call and after_call methods. These methods act as hooks that run before and after the wrapped function is executed.

By default, both methods implement pass-through behavior: before_call returns the inputs unchanged, and after_call returns the outputs unchanged.

Notes

Subclasses may override one or both methods. If a method is not overridden, the default implementation simply returns its argument unchanged.

after_call(outputs)

Hook executed after the wrapped function returns. Transform and/or inspect outputs. Must return the (possibly modified) output value.

before_call(func, inputs)

Hook executed before the wrapped function is called. Transform and/or inspect inputs. Must return a dictionary of (possibly modified) inputs.
