Interface Resolver<T>

Type Parameters:

T - the type of Binding value

All Known Implementing Classes:

ChainedResolver, ConfigurationResolver, DefaultOptionResolver, OptionalResolver, ProviderResolver, ProvidesResolver, QualifiedResolver, SystemPropertyResolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Resolver<T>

A facility to resolve Bindings for Dependencys required for injection.

A Resolver may be defined for a single type of Binding for a Dependency (monomorphic) or for numerous types of Bindings for Dependencys (polymorphic). When a Resolver implementation is monomorphic, the resolvable type should be specified using the generic parameter <T> for the Resolver. When a Resolver implementation is polymorphic, the generic parameter <T> for the Resolver should be defined as Object, and not left as a raw type.
