@ExperimentalApi("https://github.com/grpc/grpc-java/issues/4359") public enum ConnectivityState extends java.lang.Enum<ConnectivityState>
Enum Constant | Description |
---|---|
CONNECTING |
The channel is trying to establish a connection and is waiting to make progress on one of the
steps involved in name resolution, TCP connection establishment or TLS handshake.
|
IDLE |
This is the state where the channel is not even trying to create a connection because of a
lack of new or pending RPCs.
|
READY |
The channel has successfully established a connection all the way through TLS handshake (or
equivalent) and all subsequent attempt to communicate have succeeded (or are pending without
any known failure ).
|
SHUTDOWN |
This channel has started shutting down.
|
TRANSIENT_FAILURE |
There has been some transient failure (such as a TCP 3-way handshake timing out or a socket
error).
