Container initialization

Default container

If you want to initialize your basic container, just create Justdi::Container instance and use for you tasks without fear.

container = Justdi::Container.new

container.register(:orm).use_class(CustomOrm)
container.get(:orm) # => #<CustomOrm:0x0000000000000000>

Custom container

Any justdi container - is a simple wrapper over storage of dependencies (Justdi::DefinitionStore) and their resolver (Justdi::Resolver).

If you want to customize default storaging or resolving logic, you can inherit your own class from Justdi::Container like this:

class CustomContainer < Justdi::Container
  use_store    CustomStore # Should be compatible with Justdi::DefinitionStore
  use_resolver CustomResolver # Should be compatible with Justdi::Resolver
end

container = CustomContainer.new # Now you can easily create an instance

Now, for example your CustomContainer get/[], methods will forward to CustomStore, resolving functionality will use CustomResolver.
