extends Serializable
Known Direct Subinterfaces
com.mchange.v2.c3p0.QueryConnectionTester
Imports
java.io.Serializable, java.sql.Connection

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 com.mchange.v2.c3p0.UnifiedConnectionTester.

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