public abstract class AbstractMutableVirtualTable
extends AbstractVirtualTable

An abstract virtual table implementation that builds the resultset on demand and allows fine-grained source modification via INSERT/UPDATE, DELETE and TRUNCATE operations. Virtual table implementation need to be thread-safe has they can be called from different threads.
