TransactionMetaData

public class TransactionMetaData implements Serializable(Code)

This class carry transaction metadata including the transaction state.

Metadata include a transaction id, a login and a timeout. The state is used to track if a transaction is read-only or read-write and what kind of write accesses have been made in the transaction in case invalidations are needed at commit or rollback time.

The type is made serializable only for unlog messages that have to be sent between controllers.
