Method Detail

open

public void open()
          throws NotificationUserEnumerationException

Serves to initialize the enumeration. Any resources the enumeration needs may be obtained in this initialization method. This method is called before any calls to the reset, hasNext or getNext methods are made.

Specified by:

open in interface INotificationUserEnumerator

Throws

NotificationUserEnumerationException - if any problems were encountered.

reset

public void reset()
           throws NotificationUserEnumerationException

Used to reset the enumeration to the beginning. This may be necessary if a transaction got rolled back and the NotificationManager is attempting to send the notification again. <p/> It is not necessary that the enumeration proceed in the same order as it did previously, nor that the enumeration results in the same total return set-- in other words, the enumeration can be based entirely on dynamic criteria or data which may change over time. The only requirement is that an enumeration must not return the same username twice unless a call to reset() has been made.

Specified by:

reset in interface INotificationUserEnumerator

Throws

NotificationUserEnumerationException - if any problems were encountered.

hasNext

public boolean hasNext()
                throws NotificationUserEnumerationException

Used to determine if more usernames are available from this enumeration.

Specified by:

hasNext in interface INotificationUserEnumerator

Returns

true as long as more usernames are available from the enumeration.

Throws

NotificationUserEnumerationException - if any problems were encountered.

getNext

public String getNext()
               throws NotificationUserEnumerationException

Returns the next username in the enumeration.

Specified by:

getNext in interface INotificationUserEnumerator

Returns

the next username in the enumeration.

Throws

NotificationUserEnumerationException - if any problems were encountered.

close

public void close()
           throws NotificationUserEnumerationException

Releases any resources used by this enumeration.

Specified by:

close in interface INotificationUserEnumerator

Throws

NotificationUserEnumerationException - if any problems were encountered.
