Constructor Summary

PropagationImp(Stack lineage, boolean serial, long timeout)
Construct a new instance.

Method Summary

static Propagation	adaptPropagation(Propagation propagation, RecoveryCoordinator adaptor) Create a new instance.
boolean	equals(Object o) Required for JBoss integration: client demarcation depends on this.
Stack	getLineage() Get the ancestor information as a stack.
long	getTimeOut() Get the timeout left for the composite transaction.
int	hashCode() Required for JBoss integration.
boolean	isSerial() Test if serial mode or not; if serial, no parallelism allowed.

Constructor Detail

PropagationImp

public PropagationImp(Stack lineage,
                      boolean serial,
                      long timeout)

Construct a new instance.

Parameters:

lineage - The lineage stack of ancestors.

serial - Serial mode indicator.

timeout - The timeout left for the tx.

Method Detail

adaptPropagation

public static Propagation adaptPropagation(Propagation propagation,
                                           RecoveryCoordinator adaptor)

Create a new instance. This method replaces the lowest ancestor by an adaptor (interposition) for both efficiency and correct replay handling. Implementations of ImportingTransactionManager should use this method to convert an incoming propagation into the proper local instance, or replay requests will not work properly.

Parameters:

propagation - The propagation for which to create a new instance.

adaptor - The adaptor for replay requests.

getLineage

public Stack getLineage()

Description copied from interface: Propagation

Get the ancestor information as a stack.

Specified by:

getLineage in interface Propagation

Returns:

Stack The ancestor transactions.

isSerial

public boolean isSerial()

Description copied from interface: Propagation

Test if serial mode or not; if serial, no parallelism allowed.

Specified by:

isSerial in interface Propagation

Returns:

boolean True iff serial mode is set.

getTimeOut

public long getTimeOut()

Description copied from interface: Propagation

Get the timeout left for the composite transaction.

Specified by:

getTimeOut in interface Propagation

Returns:

long The time left before timeout.
