## A "callable" instance { #a-callable-instance }

In Python there's a way to make an instance of a class a "callable".

Not the class itself (which is already a callable), but an instance of that class.

To do that, we declare a method `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

    instance := grid.NewStream[*Payload, *Req, *Resp](h, newPayload, newReq, newResp)

    // Tweakable options
    instance.WithPayload = true // default true when newPayload != nil
    instance.OutCapacity = 1    // default
    instance.InCapacity = 1     // default true when newReq != nil

    // Register the handler on the manager
    instance.Register(manager, handler, "asubroute")

        "/wrapped-class-instance-dependency/",
        "/wrapped-class-instance-async-dependency/",
        "/wrapped-class-instance-gen-dependency/",
        "/wrapped-class-instance-async-gen-dependency/",
        "/class-instance-wrapped-dependency/",
        "/class-instance-wrapped-async-dependency/",
        "/class-instance-async-wrapped-dependency/",
        "/class-instance-async-wrapped-async-dependency/",

    /**
     * Creates a new instance of DataStoreFactory.
     * This constructor initializes the factory for managing data store instances
     * and provides methods for registration, retrieval, and plugin discovery.

    public DataStoreFactory() {

## Crear una instance { #create-an-instance }

Podríamos crear una instance de esta clase con:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

Y de esa manera podemos "parametrizar" nuestra dependencia, que ahora tiene `"bar"` dentro de ella, como el atributo `checker.fixed_content`.
