Class ProtocolTestAdapter

java.lang.Object
  org.apache.derby.impl.drda.ProtocolTestAdapter

public class ProtocolTestAdapter
extends java.lang.Object

Adapter written to allow for protocol testing from the test package.

The only purpose of this class is to make certain constants and methods that are package private available outside of this package for testing purposes. See DERBY-2031.
