public interface Funnel<T extends @Nullable Object>
extends Serializable
An object which can send data from an object of type
T
into a PrimitiveSink
.
Implementations for common types can be found in Funnels
.
Note that serialization of bloom filters requires the proper serialization of funnels. When possible, it is recommended that funnels be implemented as a single-element enum to maintain serialization guarantees. See Effective Java (2nd Edition), Item 3: "Enforce the singleton property with a private constructor or an enum type". For example:
public enum PersonFunnel implements Funnel<Person> {
INSTANCE;
public void funnel(Person person, PrimitiveSink into) {
into.putUnencodedChars(person.getFirstName())
.putUnencodedChars(person.getLastName())
.putInt(person.getAge());
}
}
