Class ControlImpl

final class ControlImpl extends _ControlImplBase implements Control, RecoveryCoordinator

Implements a Control interface into a transaction. Transactions are implemented strictly by TransactionImpl, however when using the OTS API or communicating with other CORBA servers it is necessary to use the control interface. This object serves as lightweight adapter between the transaction and control interface.

Control objects are produced directly only by TransactionImpl and indirectly by TransactionFactory.

Field Detail

_parents

protected final TransIdentity[] _parents

The list of parents of this transaction, the immediate parent at index 0 and the top level parent at index n-1. If this transaction is a top level, this variable is null.

_tx

protected final TransactionImpl _tx

The underlying transaction to which this control serves as an interface.

Constructor Detail

ControlImpl

ControlImpl(TransactionImpl tx, PropagationContext pgContext)

Creates a new control for a transaction that has been imported using the specified propagation context. The local transaction has it's own Xid, but no parents. The control has the parent list passed through the propagation.

Parameters: tx The local transaction pgContext The propagation context
