Interface Summary

Interface	Description
BindableService	Provides a way to bind instance of service implementation to server.
CallCredentials	Carries credential data that will be propagated to the server via request metadata for each RPC.
CallCredentials.MetadataApplier	The outlet of the produced headers.
ClientInterceptor	Interface for intercepting outgoing calls before they are dispatched by a Channel.
Codec	Encloses classes related to the compression and decompression of messages.
Compressor	Represents a message compressor.
Context.CancellationListener	A listener notified on context cancellation.
Decompressor	Represents a message decompressor.
Drainable	Extension to an InputStream or alike by adding a method that transfers all content to an OutputStream.
KnownLength	An InputStream or alike whose total number of bytes that can be read is known upfront.
Metadata.AsciiMarshaller<T>	Marshaller for metadata values that are serialized into ASCII strings that contain only following characters: Space: 0x20, but must not be at the beginning or at the end of the value.
Metadata.BinaryMarshaller<T>	Marshaller for metadata values that are serialized into raw binary.
MethodDescriptor.Marshaller<T>	A typed abstraction over message serialization and deserialization, a.k.a.
NameResolver.Listener	Receives address updates.
ServerCallHandler<RequestT,ResponseT>	Interface to initiate processing of incoming remote calls.
ServerInterceptor	Interface for intercepting incoming calls before that are dispatched by ServerCallHandler.
TransportManager.InterimTransport<T>	A transport provided as a temporary holder of new requests, which will be eventually transferred to real transports or fail.
TransportManager.OobTransportProvider<T>	A provider for out-of-band transports, usually used by a load-balancer that needs to communicate with an external load-balancing service which is under an authority different from what the channel is associated with.

Annotation Types Summary

Annotation Type	Description
ExperimentalApi	Indicates a public API that can change at any time, and has no guarantee of API stability and backward-compatibility.
Internal	Annotates a program element (class, method, package etc) which is internal to gRPC, not part of the public API, and should not be used by users of gRPC.
