Method Detail

boolean isAllowsAutoDiscovering()

Indicates whether particular exporter is available for publishing in auto-discoverable services. In general, the final solution about including particular exporter into list of services available for autodiscovered is delegated to appropriate implementation of ExporterAcceptor, however, this methods (if implementation of Exporter is aware of it) allows to disable automatic service publishing.

Returns:

true if exporter could be published for auto-discovering

getServiceGroup

java.lang.String getServiceGroup()

Services exporter by exporters may belong to serveral groups. In general, the groups of services are intended to support auto-discovering services and are less important if client uses one or more predefined services' URL's.

Groups could be used by ServicePublishers to select which services should be published and also allows to precisly control discovered services visibility on the client side.

Returns:

name of group which exported service belong to.

Returns list of URLs that could be used to locate service

Returns:
