Method Detail

getInitActivity

ActivityRef getInitActivity()

Deprecated.

Returns:

Returns the initial org.demac.process.base.dpdl.ActivityRef of the org.demac.process.base.dpdl.Transaction.

getStartActivity

ActivityRef getStartActivity()

Deprecated.

Returns:

the StartActivity of the org.demac.process.base.dpdl.Transaction.

getCompensation

Compensation getCompensation()

Deprecated.

Returns:

the org.demac.process.base.dpdl.Compensation of the org.demac.process.base.dpdl.Transaction. The compensation can itself hold Activities and Transitions to compensate the effects of the transaction if it fails.

getId

java.lang.String getId()

Deprecated.

Returns:

the ID of the org.demac.process.base.dpdl.Transaction.

getName

java.lang.String getName()

Deprecated.

Returns:

the textual name of the org.demac.process.base.dpdl.Transaction.

getRetries

int getRetries()

Deprecated.

Returns:

the number of retries for the org.demac.process.base.dpdl.Transaction.

getActivityRefs

java.util.Hashtable getActivityRefs()

Deprecated.

Returns:

the org.demac.process.base.dpdl.ActivityRefs of the org.demac.process.base.dpdl.Transaction.

getTransitions

java.util.Hashtable getTransitions()

Deprecated.

Returns:

the org.demac.process.base.dpdl.Transitions of the org.demac.process.base.dpdl.Transaction.

getType

java.lang.String getType()

Deprecated.

Returns:

the type of the transaction, for example if it should be an atomic or an open nested transaction.

hasRetries

boolean hasRetries()

Deprecated.

Method to determine whether or not a transaction should be retried.

Returns:

the retry-state

getExtendedAttributes

java.util.Hashtable getExtendedAttributes()

Deprecated.

Returns:

the org.demac.process.base.dpdl.ExtendedAttributes of the org.demac.process.base.dpdl.Transaction, for example optional information.
