absence of an injectable constructor.
Whenever Guice creates an instance, it performs this injection automatically (after first performing constructor injection), so if you're able to let Guice create all your objects for you, you'll never need to use this method.

public java.util.Map<Key<?>,Binding<?>> getBindings()
Injector
The returned map does not include bindings inherited from a parent

, should one exist. The returned map is guaranteed to iterate (for example, with
its Map.entrySet()
iterator) in the order of insertion. In other words, the order in
which bindings appear in user Modules.
This method is part of the Guice SPI and is intended for use by tools and extensions.

Injector
Just-in-time bindings created for child injectors will be created in an ancestor injector whenever possible. This allows for scoped instances to be shared between injectors. Use explicit bindings to prevent bindings from being shared with the parent injector. Optional injections in just-in-time bindings (created in the parent injector) may be silently ignored if the optional dependencies are from the child injector.
No key may be bound by both an injector and one of its ancestors. This includes just-in-time
bindings. The lone exception is the key for Injector.class
, which is bound by each
injector to itself.
