public static final SnapshotTrigger TRIGGER

A singleton instance of a SnapshotTrigger that does nothing.

Method Detail

values

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

Returns:

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

valueOf

public static NoSnapshotTriggerDefinition 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

prepareTrigger

public SnapshotTrigger prepareTrigger(@Nonnull
                                      Class<?> aggregateType)

Description copied from interface: SnapshotTriggerDefinition

Prepares a new trigger for an aggregate with the given aggregateIdentifier and aggregateType. The trigger will be notified of each event applied on the aggregate, as well as the moment at which the aggregate state is fully initialized based on its historic events.

It is highly recommended that the instances returned by this method are Serializable. Any resources that the trigger needs that are not serializable, can be reattached by implementing the SnapshotTriggerDefinition.reconfigure(Class, SnapshotTrigger) method. This method is invoked when a SnapshotTrigger has been deserialized.

Specified by:

prepareTrigger in interface SnapshotTriggerDefinition

Parameters:

aggregateType - The type of aggregate for which to create a trigger

Returns:

the trigger instance for an aggregate
