public class ReadOnlyValidatorImpl
extends 
ReadWriteValidatorImpl

A validator for read-only transactions. It provides all of the notifications (in order) that occurred during the transaction, but does not validate them (validation always passes with no problems).

A read-only validator should be created for the root transaction of any nested read-only transaction structure, when the root transaction is activated. As child transactions are activated, they must be added to me so that I may correctly track which notifications were received during which transaction, and at which time relative to the start and completion of nested transactions.
