abstract class ArtemisMessagingComponent : SingletonSerializeAsToken

config - The config object is used to pass in the passwords for the certificate KeyStore and TrustStore


Types

ArtemisAddress interface ArtemisAddress
ConnectionDirection enum class ConnectionDirection
NetworkMapAddress data class NetworkMapAddress : SingleMessageRecipient, ArtemisAddress
NodeAddress data class NodeAddress : SingleMessageRecipient, ArtemisAddress

Constructors

<init> ArtemisMessagingComponent(directory: Path, config: NodeConfiguration)

The base class for Artemis services that defines shared data structures and transport configuration

Properties

config val config: NodeConfiguration
directory val directory: Path

Functions

configureWithDevSSLCertificate fun configureWithDevSSLCertificate(): Unit

Strictly for dev only automatically construct a server certificate/private key signed from the CA certs in Node resources. Then provision KeyStores into certificates folder under node path.

tcpTransport fun tcpTransport(direction: ConnectionDirection, host: String, port: Int): <ERROR CLASS>
tryParseKeyFromQueueName fun tryParseKeyFromQueueName(queueName: <ERROR CLASS>): PublicKey?

Inherited Functions

toToken open fun toToken(context: SerializeAsTokenContext): SerializationToken

Companion Object Properties

NETWORK_MAP_ADDRESS val NETWORK_MAP_ADDRESS: <ERROR CLASS>
PEERS_PREFIX const val PEERS_PREFIX: String

Companion Object Functions

toQueueName fun toQueueName(target: MessageRecipients): <ERROR CLASS>

Assuming the passed in target address is actually an ArtemisAddress will extract the queue name used. For now the queue name is the Base58 version of the nodes identity. This should only be used in the internals of the messaging services to keep addressing opaque for the future. N.B. Marked as JvmStatic to allow use in the inherited classes.

Inheritors
