Package io.grpc.servlet.jakarta.web

Class GrpcWebServletResponse

java.lang.Object
jakarta.servlet.ServletResponseWrapper
jakarta.servlet.http.HttpServletResponseWrapper
io.grpc.servlet.jakarta.web.GrpcWebServletResponse
All Implemented Interfaces:
jakarta.servlet.http.HttpServletResponse, jakarta.servlet.ServletResponse
public class GrpcWebServletResponse extends jakarta.servlet.http.HttpServletResponseWrapper
Wraps the outgoing gRPC-web response in a way that lets the gRPC servlet/filter write normal gRPC payloads to it, and let them be translated to gRPC-web. Presently, this only means changing the content-type, and writing trailers as a streamed response.
