ServiceLookupImpl

public ServiceLookupImpl(org.refcodes.factory.CollectionFactory<Set<ServiceDescriptor<S,SCTX>>> aTypedTypeFactory)

Creates a ServiceLookupImpl for the required type.

Method Details

getServiceDescriptors

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

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

Specified by:

getServiceDescriptors in interface ServiceLookup<S extends Service<?>,SCTX>

Returns:

A collection containing the ServiceDescriptor instances known by the ServiceLookup.

hasService

public 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).

Specified by:

hasService in interface ServiceLookup<S extends Service<?>,SCTX>

Parameters:

aServiceDescriptor - the service descriptor

Returns:

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