addService

public CompletableFuture<?> addService(Service service)

Tries to dynamically add service for discovery. Method will return asynchronously after adding service to ServiceDataSource. To block till rangerHub is ready to discover service wait for future completion

Specified by:

addService in interface RangerHubClient<T,R extends ServiceRegistry<T>>

Returns:

CompletableFuture which waits for hub to be ready for discovering the new service

Throws:

UnsupportedOperationException - for any datasource which doesnt support dynamic addition of services

IllegalStateException - if called before hub is started

getDefaultDataSource

protected abstract ServiceDataSource getDefaultDataSource()

getFinderFactory

protected abstract ServiceFinderFactory<T,R> getFinderFactory()

buildHub

protected abstract ServiceFinderHub<T,R> buildHub()
