Class ProtobufKeysProvider

java.lang.Object

io.micronaut.serde.protobuf.ProtobufKeysProvider

All Implemented Interfaces:

KeysProvider

@Internal
public final class ProtobufKeysProvider
extends Object
implements KeysProvider

Contributes the property names of a Keys set to the protobuf backend.

Object properties are dispatched by index, but protobuf needs the field number the index stands for, and that is only reachable through the property name. Contributing the names here lets the encoder and decoder translate an index into a field number without a per-property lookup on the hot path.

Since:

3.2
