Interface ConnectionTester

All Superinterfaces:
java.io.Serializable
All Known Subinterfaces:
QueryConnectionTester

public interface ConnectionTester
extends java.io.Serializable

Define your own Connection tester if you want to override c3p0's default behavior for testing the validity of Connections and responding to Connection errors encountered.

Recommended: If you'd like your ConnectionTester to support the user-configured preferredTestQuery parameter, please implement QueryConnectionTester.

ConnectionTesters should be Serializable, immutable, and must have public, no-arg constructors.
