How Consumer gets object references in Dagger

How Consumer gets object references in Dagger

• In a dagger there can be multiple components and the consumer might have to get the objects from all the components
• So whatever the requirements of the consumer, The consumer requests from corresponding components.
• The component finds the object(if exists) and provides it from @Inject annotated constructor or from a @Module.
• The component could be defined at an application level, activity level, or fragment level.

Relationship between components

• Now the consumer can request in such a way that, Say consumer requests some object references from a fragment component, and the fragment component can request some object references from an application component.
• Thus there can be a relationship between the components and thus a dependency.
• Now finally the fragment component will be the one that gives the references to the consumer.
