Multiton

class Multiton<C : Any, A, T : Any>(scope: Scope<C>, contextType: TypeToken<in C>, explicitContext: Boolean, argType: TypeToken<in A>, createdType: TypeToken<out T>, refMaker: RefMaker?, sync: Boolean, creator: BindingDI<C>.(A) -> T) : DIBinding<C, A, T>

Concrete multiton: will create one and only one instance for each argument. Will create the instance on first time a given argument is used and will subsequently always return the same instance for the same argument.

Parameters

The created type.
