Class ContextInjectingInterceptor

java.lang.Object

io.camunda.zeebe.gateway.interceptors.impl.ContextInjectingInterceptor

All Implemented Interfaces:

io.grpc.ServerInterceptor

public final class ContextInjectingInterceptor
extends Object
implements io.grpc.ServerInterceptor

An interceptor implementation which injects common context for further interceptors. It's expected to be one of the top level interceptors. This is for context objects which are the same and shared by all interceptors, as opposed to the DecoratedInterceptor which injects context information specific to the wrapped interceptor.

This interceptor will inject the following in every call's context:

• InterceptorUtil#getQueryApi() => returns a query API usable by the interceptors
