| |
| <p>The initial state of a Subchannel is IDLE. You won't get a notification for the initial IDLE |
| state. |
| |
| <p>If the new state is not SHUTDOWN, this method should create a new picker and call <a href="../LoadBalancer.Helper.html#updateBalancingState(io.grpc.ConnectivityState,io.grpc.LoadBalancer.SubchannelPicker)"><code>Helper.updateBalancingState()</code></a>. Failing to do so may result in |
| unnecessary delays of RPCs. Please refer to <a href="../LoadBalancer.PickResult.html#withSubchannel(io.grpc.LoadBalancer.Subchannel,io.grpc.ClientStreamTracer.Factory)"><code>PickResult.withSubchannel()</code></a>'s javadoc for more information. |
| |
| <p>SHUTDOWN can only happen in two cases. One is that LoadBalancer called <a href="../LoadBalancer.Subchannel.html#shutdown()"><code>LoadBalancer.Subchannel.shutdown()</code></a> earlier, thus it should have already discarded this Subchannel. The other |
| is that Channel is doing a <a href="../ManagedChannel.html#shutdownNow()"><code>forced shutdown</code></a> or has already |
| terminated, thus there won't be further requests to LoadBalancer. Therefore, the LoadBalancer |
| usually don't need to react to a SHUTDOWN state.</div> |
