Class InstantiatingGrpcChannelProvider

java.lang.Object

com.google.api.gax.grpc.InstantiatingGrpcChannelProvider

All Implemented Interfaces:

TransportChannelProvider

@InternalExtensionOnly
public final class InstantiatingGrpcChannelProvider
extends Object
implements TransportChannelProvider

InstantiatingGrpcChannelProvider is a TransportChannelProvider which constructs a gRPC ManagedChannel with a number of configured inputs every time getChannel(...) is called. These inputs include a port, a service address, and credentials.

The credentials can either be supplied directly (by providing a FixedCredentialsProvider to Builder.setCredentialsProvider()) or acquired implicitly from Application Default Credentials (by providing a GoogleCredentialsProvider to Builder.setCredentialsProvider()).

The client lib header and generator header values are used to form a value that goes into the http header of requests to the service.
