Interface RpcTransport

All Known Implementing Classes:

NetworkTransport

public interface RpcTransport

The one HTTP exchange every chain client needs: send a body, read the reply. The clients in this package are written against this interface alone, so the same EvmRpc, EsploraClient and SolanaRpc run in an application and on the backend:

• in an application, NetworkTransport sends through the NetworkManager;
• on the backend, com.codename1.backend.WebRpcTransport sends through its WebClient.

A test passes its own implementation that answers recorded replies.

Every call blocks until the reply arrives. On the EDT the application transport waits with invokeAndBlock, as NetworkManager.addToQueueAndWait does, so the UI keeps painting.
