Similar to "isActive" except that it just returns the "active" flag whereas the isActive() method can also embody rejoining to underlying transactions.boolean

getIsActive
public boolean getIsActive()Description copied from class:TransactionImpl
Similar to "isActive" except that it just returns the "active" flag whereas the isActive() method can also embody rejoining to underlying transactions.- Specified by:
getIsActive
in interfaceTransaction
- Overrides:
getIsActive
in classTransactionImpl
- Returns:
- The "active" flag
-
isActive
public boolean isActive()Accessor for whether the transaction is active.- Specified by:
isActive
in interfaceTransaction
- Overrides:
isActive
in classTransactionImpl
- Returns:
- Whether the transaction is active.
-
joinTransaction
private void joinTransaction()Synchronise our active state with that of the JTA transaction, if it exists. Look for an active JTA transaction. If there is one, begin() ourselves and register synchronisation. We must poll because there is no way of getting notified of a newly begun transaction. -
beforeCompletion
public void beforeCompletion()Called by the transaction manager prior to the start of the two-phase transaction commit process.- Specified by:
beforeCompletion
in interfaceSynchronization
-
afterCompletion
public void afterCompletion(int status) Called by the transaction manager after the transaction is committed or rolled back. Must be synchronised because some callers expect to be owner of this object's monitor (internalPostCommit() calls closeSQLConnection() which calls notifyAll()).- Specified by:
afterCompletion
in interfaceSynchronization
- Parameters:
status
- The status
