All Implemented Interfaces:

SqlTypeFactory

public class SqlComposedTypeFactory
extends Object
implements SqlTypeFactory

The factory definition, which can be used to construct the SqlMetaType instances. It's used to combine the factory of the underlying stack (on top of which the SQL Processor works) and the custom META types provided in the time of SqlProcessorLoader construction.
