const mixinafConcurrent::LocalRefManager

(Service) - Use to create LocalRef / LocalList / LocalMap instances whose contents can be cleaned up. Erm, I mean deleted!

This is particularly important in the context of web applications where resources need to be cleaned up at the end of a web request / thread.

Then when cleanUpThread() is called, all thread local data created by this manager will be deleted from Actor.locals

LocalRefManager is automatically made available in IoC enabled applications.

LocalXXX Injection

The Concurrent library also defines an IoC DependencyProvider that injects LocalXXX instances directly into your class. Where possible, the field name is used as the local name. Example:

const class Example {
    @Inject const LocalMap localMap

    new make(|This|in) { in(this) }
}

@Inject.type may be used to declare the underlying parameters of the LocalList / LocalMap:

const class Example {
    @Inject { type=Str[]# }
    const LocalList localList

    @Inject { type=[Str:Slot?]# }
    const LocalMap localMap

    new make(|This|in) { in(this) }
}

If @Inject.type is used with a LocalMap, then if the key is a Str the map will be case-insensitive, otherwise it will be ordered.
