ArtemisMessagingComponent |
abstract class ArtemisMessagingComponent : SingletonSerializeAsToken The base class for Artemis services that defines shared data structures and SSL transport configuration. |
ArtemisMessagingServer |
class ArtemisMessagingServer : ArtemisMessagingComponent This class configures and manages an Apache Artemis message queue broker. |
ClassSerializer |
object ClassSerializer |
ClientRPCRequestMessage |
data class ClientRPCRequestMessage The contents of an RPC request message, separated from the MQ layer. |
CordaRPCClient |
class CordaRPCClient : Closeable, ArtemisMessagingComponent An RPC client connects to the specified server and allows you to make calls to the server that perform various useful tasks. See the documentation for proxy or review the docsite to learn more about how this API works. |
CordaRPCClientImpl |
class CordaRPCClientImpl Core RPC engine implementation, to learn how to use RPC you should be looking at CordaRPCClient. |
MarshalledObservation |
data class MarshalledObservation Used in the RPC wire protocol to wrap an observation with the handle of the observable its intended for. |
NodeLoginModule |
class NodeLoginModule : LoginModule Clients must connect to us with a username and password and must use TLS. If a someone connects with ArtemisMessagingComponent.NODE_USER then we confirm its just us as the node by checking their TLS certificate is the same as our one in our key store. Then theyre given full access to all valid queues. If they connect with ArtemisMessagingComponent.PEER_USER then we confirm they belong on our P2P network by checking their root CA is the same as our root CA. If thats the case the only access theyre given is the ablility send to our P2P address. In both cases the messages these authenticated nodes send to us are tagged with their subject DN and we assume the CN within that is their legal name. Otherwise if the username is neither of the above we assume its an RPC user and authenticate against our list of valid RPC users. RPC clients are given permission to perform RPC and nothing else. |
NodeMessagingClient |
class NodeMessagingClient : ArtemisMessagingComponent, MessagingServiceInternal This class implements the MessagingService API using Apache Artemis, the successor to their ActiveMQ product. Artemis is a message queue broker and here we run a client connecting to the specified broker instance ArtemisMessagingServer. Its primarily concerned with peer-to-peer messaging. |
RPCDispatcher |
abstract class RPCDispatcher Intended to service transient clients only (not p2p nodes) for short-lived, transient request/response pairs. If you need robustness, this is the wrong system. If you dont want a response, this is probably the wrong system (you could just send a message). If you want complex customisation of how requests/responses are handled, this is probably the wrong system. |
VerifyingNettyConnectorFactory |
class VerifyingNettyConnectorFactory |
RPCSinceVersion |
annotation class RPCSinceVersion Records the protocol version in which this RPC was added. |
PermissionException |
class PermissionException : RuntimeException |
RPCException |
open class RPCException : RuntimeException Thrown to indicate a fatal error in the RPC system itself, as opposed to an error generated by the invoked method. |
CURRENT_RPC_USER |
val CURRENT_RPC_USER: ThreadLocal<User> This is available to RPC implementations to query the validated User that is calling it. Each user has a set of permissions theyre entitled to which can be used to control access. |
rpcLog |
val rpcLog: <ERROR CLASS> Global RPC logger |
createRPCKryo |
fun createRPCKryo(observableSerializer: <ERROR CLASS><<ERROR CLASS><Any>>? = null): <ERROR CLASS> |
requirePermission |
fun requirePermission(permission: String): Unit Helper method which checks that the current RPC user is entitled for the given permission. Throws a PermissionException otherwise. |
