All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<AccumulationMode>

public enum AccumulationMode
extends java.lang.Enum<AccumulationMode>

Specifies how a Window should process its previously emitted WindowPanes.

There are two types of AccumulationModes:

• ACCUMULATING: Specifies that window panes should include all messages collected for the window (key) so far, even if they were included in previously emitted window panes.
• DISCARDING: Specifies that window panes should only include messages collected for this window (key) since the last emitted window pane.

Method Detail

values

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

Returns:

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

valueOf

public static AccumulationMode valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
