Activities:
annotation is allowed on interfaces to define a set of activities. This interface forms the contract between the implementation of the activities and the clients used to invoke them. The client-side is auto-generated by AWS Flow Framework annotation processor from the interfaces marked with @Activities annotation. Each method on the interface annotated with @Activities annotation corresponds to an activity. Activity methods are not allowed to have com.amazonaws.services.simpleworkflow.flow.core.Promise parameters or return types.
public @interface Activities {

    
Prefix to use for each activity defined within the interface annotated with

Activities:
annotation. Default is empty string which means that name of interface should be used as the prefix for each activity name.
    String activityNamePrefix() default "";

    
Version to use to each activity defined within the interface annotated with

Activities:
annotation. Default is empty string which means that version should be specified using Activity.version() on every method individually. Alternatively you can specify the version for all activities defined within the interface using this attribute. AWS Flow Framework annotation processor will report an error if version for an activity is not specified through Activities.version() or Activity.version().
    String version() default "";

    
This is used to specify DataConverter type to use for serialization/de-serialization of activity method parameters and return types. Default is NullDataConverter which means to use the default DataConverter used by framework. Default DataConverter used by framework is JsonDataConverter.
    Class<? extends DataConverterdataConverter() default NullDataConverter.class;
