Method Detail

withScope

public Provider<T> withScope(Key<?> match,
                             Scope scope)

Description copied from class: StdProvider

Adds the control of scoping the provider. Used by scoped providers (that check if the scope is the same, and return the same provider) and some other providers like InstanceProvider that doesn't support scopes and throws an exception.

Scopes the provider with the given scope

Overrides:

withScope in class StdProvider<T>

Parameters:

match - The key used to match the scope

scope - The scope to apply

Returns:

The scope applied to the provider, the providers are externally immutable, so this shouldn't modify the real provider and returns another provider or the same provider

                   InjectorImpl injector)

Description copied from class: StdProvider
