Package io.grpc.opentelemetry

Class MetadataSetter

java.lang.Object

io.grpc.opentelemetry.MetadataSetter

All Implemented Interfaces:

io.opentelemetry.context.propagation.TextMapSetter<io.grpc.Metadata>

final class MetadataSetter
extends java.lang.Object
implements io.opentelemetry.context.propagation.TextMapSetter<io.grpc.Metadata>

A TextMapSetter that sets value to gRPC Metadata. Supports both text and binary headers. Supporting binary header is an optimization path for GrpcTraceBinContextPropagator to work around the lack of binary propagator API and thus avoid base64 (de)encoding when passing data between propagator API interfaces.
