Threading

ThreadLocal

The class ThreadLocal is a simple generic wrapper around threading.local

After creating an instance with ThreadLocal[type]() you can use the methods: - get(self) -> Optional[T] - set(self, value: T) -> None - clear(self)

An optional constructor argument serves as a factory that is called in the get methiod whenever no value i set.

ContextLocal

A similar class ContextLocal is implemented that uses ContextVars. In addition it defines a use method as a @contextmanager

Synchronized

A handy decorator @synchronized in combination with the respective advice is implemented that automatically synchronizes methods with a RLock associated with the instance.

Example:

@injectable()
class Foo:
    @synchronized()
    def execute_synchronized(self):
        ...
