Enum Constant Detail

EVENT_TRACKING_OFF

public static final GridStreamerIndexPolicy EVENT_TRACKING_OFF

Do not track events.

Only a value, generated by GridStreamerIndexUpdater, will be stored in an index; event objects will be thrown away.

EVENT_TRACKING_ON

public static final GridStreamerIndexPolicy EVENT_TRACKING_ON

Track events.

All event objects will stored in an index along with the values, generated by GridStreamerIndexUpdater.

EVENT_TRACKING_ON_DEDUP

public static final GridStreamerIndexPolicy EVENT_TRACKING_ON_DEDUP

Track events with de-duplication.

All event objects will stored in an index along with the values, generated by GridStreamerIndexUpdater. For duplicate (equal) events, only a single event object will be stored, which corresponds to a first event.

Method Detail

values

public static GridStreamerIndexPolicy[] 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 (GridStreamerIndexPolicy c : GridStreamerIndexPolicy.values())
    System.out.println(c);

Returns:

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

valueOf

public static GridStreamerIndexPolicy 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
