@DoNotImplement public RPCOps
Base interface that all RPC servers must implement. Note: in Corda there's only one RPC interface. This base interface is here in case we split the RPC system out into a separate library one day.
int getProtocolVersion()
Returns the RPC protocol version. Exists since version 0 so guaranteed to be present.
Getting this property is handled as a quick RPC, meaning that it is handled outside the node's standard thread pool in order to provide a quick response even when the node is dealing with a high volume of RPC calls.
