Interface ConnectionTester

All Superinterfaces:
Serializable
All Known Subinterfaces:
FullQueryConnectionTester, QueryConnectionTester, UnifiedConnectionTester

public interface ConnectionTester extends 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 UnifiedConnectionTester.

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