UndoableDomainObject
extends a domain object to provide transaction
support and the ability to undo and redo changes made within a stack of
recent transactions. Each transactions may contain many sub-transactions which
reflect concurrent changes to the domain object. If any sub-transaction fails to commit,
all concurrent sub-transaction changes will be rolled-back.
NOTE: A transaction must be started in order to make any change to this domain object - failure to do so will result in a IOException.

Method Details
-
startTransaction
Start a new transaction in order to make changes to this domain object. All changes must be made in the context of a transaction. If a transaction is already in progress, a sub-transaction of the current transaction will be returned.- Parameters:
description
- brief description of transaction- Returns:
- transaction ID
- Throws:
DomainObjectLockedException
- the domain object is currently lockedTerminatedTransactionException
- an existing transaction which has not yet ended was terminated early. Sub-transactions are not permitted until the terminated transaction ends.
-
startTransaction
Start a new transaction in order to make changes to this domain object. All changes must be made in the context of a transaction. If a transaction is already in progress, a sub-transaction of the current transaction will be returned.- Parameters:
description
- brief description of transactionlistener
- listener to be notified if the transaction is aborted.- Returns:
- transaction ID
- Throws:
DomainObjectLockedException
- the domain object is currently lockedTerminatedTransactionException
- an existing transaction which has not yet ended was terminated early. Sub-transactions are not permitted until the terminated transaction ends.
-
endTransaction
void endTransaction(int transactionID, boolean commit) Terminate the specified transaction for this domain object.- Parameters:
transactionID
- transaction ID obtained from startTransaction methodcommit
- if true the changes made in this transaction will be marked for commit, if false this and any concurrent transaction will be rolled-back.
-
getCurrentTransaction
Transaction getCurrentTransaction()Returns the current transaction- Returns:
- the current transaction
-
hasTerminatedTransaction
boolean hasTerminatedTransaction()Returns true if the last transaction was terminated externally from the action that started it. -
getSynchronizedDomainObjects
DomainObject[] getSynchronizedDomainObjects()Return array of all domain objects synchronized with a shared transaction manager.- Returns:
- returns array of synchronized domain objects or null if this domain object is not synchronized with others.
-
addSynchronizedDomainObject
Synchronize the specified domain object with this domain object using a shared transaction manager. If either or both is already shared, a transition to a single shared transaction manager will be performed.- Parameters:
domainObj
-- Throws:
LockException
- if lock or open transaction is active on either this or the specified domain object
-
releaseSynchronizedDomainObject
Remove this domain object from a shared transaction manager. If this object has not been synchronized with others via a shared transaction manager, this method will have no affect.- Throws:
LockException
- if lock or open transaction is active
-
