Class MemorizeTransactionProxy

java.lang.Object

com.jolbox.bonecp.MemorizeTransactionProxy

All Implemented Interfaces:

InvocationHandler

public class MemorizeTransactionProxy
extends Object
implements InvocationHandler

This code takes care of recording and playing back of transactions (when a failure occurs). The idea behind this is to wrap a connection or statement with proxies and log all method calls. When a failure occurs, thrash the inner connection, obtain a new one and play back the previously recorded methods.
