/**
 * Factory interface for creating local adapters for remote references.
 * This interface defines how remote JCR-RMI references are adapted
 * back to the normal JCR interfaces. The adaption mechanism can be
 * modified (for example to add extra features) by changing the
 * local adapter factory used by the repository client.
 * <p>
 * Note that the
 * {@link org.apache.jackrabbit.rmi.client.ClientObject ClientObject}
 * base class provides a number of utility methods designed to work with
 * a local adapter factory. Adapter implementations may want to inherit
 * that functionality by subclassing from ClientObject.
