Enum Constant Detail

REALTIME

public static final ListenerPriority REALTIME

Provide access to events in near real time for specialised services that need priority access to events. Realtime events are sent before any other listeners get a chance to process the events. With the event dispatcher running in its own thread. This means that they are passed without delay. You must also ensure that you don't delay the processing of these messages as there may be real time event listeners. If you are concerned that you are going to delay the processing then you need to add in your own ManagerEventQueue to insulate other priority listeners from your tardiness. NOTE: you cannot rely on the LiveChannelManager as it processes events from the standard event queue. This means that Rename and Masquerade events MAY (very likely) not have been process when the realtime listener recieves an event.

Method Detail

values

public static ListenerPriority[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ListenerPriority c : ListenerPriority.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ListenerPriority valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

compare

public int compare(ListenerPriority rhs)
