Enum Constant Detail

INSTANCE

public static final DirectEventProcessingStrategy INSTANCE

Singleton instance of the DirectEventProcessingStrategy.

Method Detail

values

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

Returns:

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

valueOf

public static DirectEventProcessingStrategy 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

handle

public void handle(@Nonnull
                   List<? extends EventMessage<?>> events,
                   @Nonnull
                   Consumer<List<? extends EventMessage<?>>> processor)

Description copied from interface: EventProcessingStrategy

Handle the given batch of events. Once the strategy decides it is opportune to process the events it should pass them back to the given processor.

Note that the strategy may call back to the processor more than once for a single invocation of this method. Also note that a batch of events passed back to the processor may be made up of events from different batches.

Specified by:

handle in interface EventProcessingStrategy

Parameters:

events - Events to be processed

processor - Callback method on the processor that carries out the actual processing of events
