Protected ReadOnly Property ReadLock As IDisposable
An object that can be used to establish a lock on the data table members and then be appropriately disposed with a using
construct.
In derived classes, queries to the table contained in Item[] should always occur within a using (ReadLock) { ... }
clause, except for queries that are already within a write lock. These queries may be necessary if your class supports a more sophisticated AddListener
implementation that requires more data beyond the source
and the listener
, and uses the Item[] collection to store the extra information.
