Method Detail

asyncCommit

void asyncCommit(CommitListener listener)
                 throws IllegalStateException,
                        SecurityException

Request that the transaction represented by this SleeTransaction object asynchronously commit. The calling thread is not required to have this transaction associated with the thread. The transaction must be currently active (Status.STATUS_ACTIVE) or marked for rollback (Status.STATUS_MARKED_ROLLBACK). This method initiates the commit operation and may return before the transaction completes. If any threads are associated with the transaction then those associations are cleared before this method returns.

If the transaction has been marked for rollback, or if execution of any Synchronization callbacks cause it to be marked for rollback, then a rollback will be started (equivalent to calling asyncRollback(javax.slee.transaction.RollbackListener)).

At some point after calling this method, the transaction state will become either Status.STATUS_COMMITTED or Status.STATUS_ROLLEDBACK.

Parameters:

listener - listener object that will receive callbacks depending on the final outcome of the transaction. If this argument is null, no callbacks will be made by the SLEE.

Throws:

IllegalStateException - if the transaction is not in the active or marked for rollback state.

SecurityException - if the current thread is not allowed to commit the transaction.

asyncRollback

void asyncRollback(RollbackListener listener)
                   throws IllegalStateException,
                          SecurityException

Request that the transaction represented by this SleeTransaction object asynchronously roll back. The calling thread is not required to have this transaction associated with the thread. The transaction must be currently active (Status.STATUS_ACTIVE) or marked for rollback (Status.STATUS_MARKED_ROLLBACK). This method initiates the rollback operation and may return before the transaction completes. If any thread are associated with the transaction then those associations are cleared before this method returns.

At some point after calling this method, the transaction state will become Status.STATUS_ROLLEDBACK.

Parameters:

listener - listener object that will receive callbacks depending on the final outcome of the transaction. If this argument is null, no callbacks will be made by the SLEE.

Throws:

IllegalStateException - if the transactions is not in the active or marked for rollback state.

SecurityException - if the current thread is not allowed to roll back the transaction.

enlistResource

boolean enlistResource(XAResource resource)
                       throws IllegalStateException,
                              RollbackException

This method, defined by the JTA Transaction interface, has no defined behavior in SLEE 1.1.

Throws:

IllegalStateException

RollbackException

delistResource

boolean delistResource(XAResource resource,
                     int flag)
                       throws IllegalStateException,
                              SystemException

This method, defined by the JTA Transaction interface, has no defined behavior in SLEE 1.1.

Throws:

IllegalStateException

SystemException

equals

boolean equals(Object obj)

Compare this SLEE Transaction object for equality with another object.

Overrides:

equals in class Object

Parameters:

obj - the object to compare this with.

Returns:

true if obj is a SleeTransaction object that represents the same transaction as this, false otherwise.

See Also:

Object.equals(Object)

hashCode

int hashCode()

Get a hash code value for the transaction represented by this SLEE Transaction object. Two SleeTransaction objects t1 and t2 must return the same hash code if t1.equals(t2).

Overrides:

hashCode in class Object

Returns:

a hash code value for this SLEE Transaction object.

See Also:

Object.hashCode()

toString

String toString()

Get a string representation for the transaction represented by this SleeTransaction object. For any two SleeTransaction objects t1 and t2:

• if t1 and t2 represent the same transaction, ie. t1.equals(t2), then t1.toString().equals(t2.toString()) must hold true.
• if t1 and t2 represent different transactions, then !t1.toString().equals(t2.toString()) must hold true.

Overrides:

toString in class Object

Returns:

a string representation for the transaction.

Object.toString()
