Class GroupBasedExporterAcceptor<AE extends AutoDiscoveredServiceExporter,SP extends ServicePublisher>

java.lang.Object
  org.softamis.cluster4spring.support.context.DefaultExporterAcceptor<AE,SP>
      org.softamis.cluster4spring.support.context.GroupBasedExporterAcceptor<AE,SP>

Type Parameters:

AE - type of service exporter

SP - type of service publisher

All Implemented Interfaces:

ExporterAcceptor<AE,SP>

public class GroupBasedExporterAcceptor<AE extends AutoDiscoveredServiceExporter,SP extends ServicePublisher>
extends DefaultExporterAcceptor<AE,SP>

Policy that accepts all exporters which has allowsAutoDiscovering property set to true and group equals to publisher' group. This policy is useful if the same server serves several clients and services published for one client should not be availalble for another one. This could be done by separating all own services on the server by groups and using different publishers for each group.
