autowire.impl package

Submodules

autowire.impl.function module

impl.function

Function implementation classes

class autowire.impl.function.FunctionImplementation(function: function, evaluator: function)

Bases: autowire.base.Implementation

Implementation with wrapping function and evaluator

Parameters:

• function – function to be wrapped.
• evaluator ((Function, BaseResource, BaseContext) -> ContextManager) – function evaluator for reifying.

reify(resource: autowire.base.BaseResource, context: autowire.base.BaseContext)

autowire.impl.implementable module

impl.implementable

Abstract base class for implementable things.

class autowire.impl.implementable.Implementable

Bases: object

Some type that can be implemented

implement(implementation: autowire.base.Implementation) → autowire.base.Implementation

Implement this.

It returns given implementation so that can be used as a decorator.

Module contents

impl

Implementers.

autowire.impl.implementation(fn)

Create an implmentation with function that compatible with reify method.

The implementation can be called same as original function.

autowire.impl.contextual(fn)

Create an implementation with function that returns context manager.

The implementation can be called same as original function.

autowire.impl.plain(fn)

Create an implementation with plain function.

The implementation can be called same as original function.

autowire.impl.autowired(argname_or_required, required=None)

Resolve a required resource and inject into function implementation as keyword argument.

dependency = Resource('foo', __name__)

@autowired('dependency', dependency)
@impl.plain
def create_something(dependency):
    return create(dependency)

Resource’s name property will be used by default for keyword name.

dependency = Resource('foo', __name__)

@autowired(dependency)
@impl.plain
def create_something(foo):
    return create(foo)

class autowire.impl.Implementation

Bases: object

Base implementation type

reify(resource: autowire.base.BaseResource, context: autowire.base.BaseContext)

class autowire.impl.Implementable

Bases: object

Some type that can be implemented

implement(implementation: autowire.base.Implementation) → autowire.base.Implementation

Implement this.

It returns given implementation so that can be used as a decorator.
