Interface TransactionHandler

All Known Implementing Classes:
CMTTransactionHandler, DelegatingTransactionHandler, LocalTransactionHandler, RollbackOnlyTransactionHandler, SerializableTransactionRunner
public interface TransactionHandler
Interface which defines callbacks to be used when transaction methods are called on a handle. Used by specifying on a Jdbi instance. All Handle instances opened from that Jdbi will use the handler specified.

The default implementation, LocalTransactionHandler, explicitly manages the transactions on the underlying JDBC Connection.
