withScope

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

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

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

inject

public void inject(ProvisionStack stack,
                   InjectorImpl injector)

Used by standard providers and some other providers to delegate the injection to the wrapped provider (when it's a wrapper provider) or injecting some provider properties without checking everything

Parameters:

stack - The thread injection stack (passed as argument instead of getting it from the thread-local held by the injector)

injector - The injector used to inject this provider

onBind

public boolean onBind(BinderImpl binder,
                      Key<?> key)

Listener method called when the provider is bound. Commonly this is called immediately after the construction.

Adds the control of the binding to the provider, used by standard providers to replace bindings and some other things.

Parameters:

binder - The binder used to bind this provider

key - The bound key

Returns:

False if the binding must be removed (handled by the binder) this is used for special providers like the ToFactoryProvider that converts its binding to another binding. (Removes its binding and adds another one)
