Element Detail

namespace

public abstract String namespace

Optional identification of the namespace of the domain event handled by this handler. This information may be used for easier linkage between event and handler by external tools and refers to DomainEvent.namespace(). When leaving the default value, it is assumed that the method signature makes clear what event is consumed. If the handler takes care of all events of a specific namespace, the value of this field needs to be set to the respective namespace and the name() needs to be set accordingly. If the handler doesn't care about the namespace, the value may be set to the '*' (asterisk) placeholder.

Default:

""
