@FunctionalInterface public static interface CoprocessorHost.ObserverGetter<C,O> extends Function<C,Optional<O>>
O
from a coprocessor of
type C
. Concrete implementations of CoprocessorHost define one getter for each observer
they can handle. For e.g. RegionCoprocessorHost will use 3 getters, one for each of
RegionObserver, EndpointObserver and BulkLoadObserver. These getters are used by
ObserverOperation
to get appropriate observer from the coprocessor.Copyright © 2007–2020 The Apache Software Foundation. All rights reserved.
