Class ManagedJdbcTransactionContext

java.lang.Object

org.j7m.middleware.application.distributed.ManagedJdbcTransactionContext

public final class ManagedJdbcTransactionContext
extends Object

Invocation-bound local H2 JDBC unit of work. The host owns its one physical connection. Application SQL and JdbcDelivery share one stable guarded Connection. The guard supports only the declared finite H2 data subset, not transaction control, DDL, procedures, vendor unwrapping, savepoints or arbitrary SQL sandboxing. USER work is serial; results must be detached data before settlement. JDBC/LOB/stream handles cannot be used by a codec or after USER seal.

Method Summary

Modifier and Type	Method	Description
Connection	connection()	Returns the same guarded connection for every access in this actual transaction.
boolean	rollbackOnly()	Returns whether the transaction must roll back rather than commit.
void	setRollbackOnly()	Marks the entire REQUIRED unit of work rollback-only; no nested caller can clear the flag.

Returns:

borrowed stable guarded connection

Throws:

SQLException - outside the owning open USER scope or before successful admission

setRollbackOnly

public void setRollbackOnly()
                     throws SQLException

Marks the entire REQUIRED unit of work rollback-only; no nested caller can clear the flag.

Throws:

SQLException - outside the owning open USER phase

rollbackOnly

public boolean rollbackOnly()

Returns whether the transaction must roll back rather than commit.

sticky rollback-only state
