Method Detail

getBufferedUpdates

public ListEventAssembler<E> getBufferedUpdates()

beginEvent

public void beginEvent()

Demarks the beginning of a transaction which accumulates all ListEvents received during the transaction and fires a single aggregate ListEvent on commitEvent().

beginEvent

public void beginEvent(boolean buffered)

Demarks the beginning of a transaction. If buffered is true then all ListEvents received during the transaction are accumulated and fired as a single aggregate ListEvent on commitEvent(). If buffered is false then all ListEvents received during the transaction are forwarded immediately and commitEvent() produces no ListEvent of its own.

Parameters:

buffered - true indicates ListEvents should be buffered and sent on commitEvent(); false indicates they should be sent on immediately

commitEvent

public void commitEvent()

Demarks the successful completion of a transaction. If changes were buffered during the transaction by calling beginEvent(true) then a single ListEvent will be fired from this TransactionList describing the changes accumulated during the transaction.

rollbackEvent

public void rollbackEvent()

Demarks the unsuccessful completion of a transaction. If changes were NOT buffered during the transaction by calling beginEvent(false) then a single ListEvent will be fired from this TransactionList describing the rollback of the changes accumulated during the transaction.

dispose

public void dispose()

addListEventListener

public void addListEventListener(ListEventListener<? super E> listChangeListener)

removeListEventListener

public void removeListEventListener(ListEventListener<? super E> listChangeListener)
