Package ratpack.exec.registry

Registries hold objects that can be retrieved via type, and are a key aspect of Ratpack applications.

Registries are primarily used for inter Handler communication in request processing. The Context object that handles operate on implements the Registry interface.

See Registry for examples of how registries are used by handlers.
