public abstract class FXAccountEvent
extends FXEvent

The FXAccountEvent class is the abstract superclass of all events which will be fired in response to a new transaction done on an account. An FXAccountEvent can filter incoming transactions by setting a key corresponding to a desired transaction's getType() value. If a key is set, the match method will only be called for transactions with the given type.
