Method Detail

getServiceDescriptors

Set<ServiceDescriptor<S,SCTX>> getServiceDescriptors()

Returns a collection containing the ServiceDescriptor instances known by the ServiceLookup.

Returns:

A collection containing the ServiceDescriptor instances known by the ServiceLookup.

hasService

boolean hasService(ServiceDescriptor<S,SCTX> aServiceDescriptor)

Determines whether the given service is known by the service bus by taking the service type and the service meta data as criteria, not the service identity. I.e. there must not be the same service twice on the service bus which can not be distinguished by its type and its meta data (i.e. a matcher must be able to distinguish two services from each other).

Parameters:

aService - The service for which to test if it is known to the service bus.

Returns:

True in case the given service is known by the service bus.
