Imports

java.lang.reflect.Constructor, java.util.HashMap, .Map, com.sun.tools.xjc.ErrorReceiver, com.sun.tools.xjc.model.Model

Holds all the binding related singleton components in a "ring", and let you access those components, creating them as necessary.

A Ring is local to a thread, and only one instanceof Ring can be active at any given time. Use begin() and end(Ring) to start/end a ring scope. Inside a scope, use get() to obtain the instance.

When a Model is built by the reader, an active Ring scope is assumed.

Components in Ring

Depending on the schema language we are dealing with, different components are in the model. But at least the following components are in the ring.
