Interface DynamicBindingProvider<T>

public interface DynamicBindingProvider<T>

A special Guice provider that can get an instance of a binding for a dynamically determined binding annotation.

This class allows providers and modules to be assigned a binding annotation at runtime, rather than compile time, and then use that binding annotation to retrieve bindings for that annotation.

Warning: It is rarely a good idea to expose instances of this provider globally. Ideally these should be used within a PrivateModule or AnnotatedModule and kept within the scope of those modules. There is still benefit from using a dynamic binding provider in this way and then exposing downstream types that can be built from the dynamic binding provider.
