Features

By default, you can use methods to register with lifetime:

• register_singleton(key, factory)
• register_scoped(key, factory)
• register_transient(key, factory)
• register(key, factory, lifetime)
• register_value(key, value)
• register_group(key, keys)
• register_bind(new_key, target_key)

Predefined keys

There are some predefined keys you can use direct, but you still can overwrite it:

• ioc - get current scoped ServiceProvider instance.
• provider - alias of ioc
• service_provider - alias of ioc

provider.get() vs provider[]

provider[] will raise ServiceNotFoundError when service was not found;

provider.get() only return None without error.

IServiceInfoResolver

By default, you need to register a service before you get it.

So if you want to dynamic get it without register:

from anyioc import ServiceProvider
from anyioc.symbols import Symbols
from anyioc.ioc_resolver import ImportServiceInfoResolver

import sys
provider = ServiceProvider()
provider[Symbols.missing_resolver].append(ImportServiceInfoResolver())
assert sys is provider['sys']

There are other builtin resolvers:

• ImportServiceInfoResolver - import a module from a str key
• TypesServiceInfoResolver - create instance from a type key
• TypeNameServiceInfoResolver - from str key find a type, then create instance
