abstract val notaryHandles: List<NotaryHandle>

Returns a list of NotaryHandles matching the list of NotarySpecs passed into driver.



abstract fun baseDirectory(nodeName: CordaX500Name): Path

Returns the base directory for a node with the given CordaX500Name. This method is useful if the base directory is needed before the node is started.


abstract fun startNode(defaultParameters: NodeParameters = NodeParameters(), providedName: CordaX500Name? = defaultParameters.providedName, rpcUsers: List<User> = defaultParameters.rpcUsers, verifierType: VerifierType = defaultParameters.verifierType, customOverrides: Map<String, Any?> = defaultParameters.customOverrides, startInSameProcess: Boolean? = defaultParameters.startInSameProcess, maximumHeapSize: String = defaultParameters.maximumHeapSize): CordaFuture<NodeHandle>

Start a node.

open fun startNode(parameters: NodeParameters): CordaFuture<NodeHandle>

Helper function for starting a Node with custom parameters from Java.


open fun startWebserver(handle: NodeHandle): CordaFuture<WebserverHandle>

Call startWebserver with a default maximumHeapSize.

abstract fun startWebserver(handle: NodeHandle, maximumHeapSize: String): CordaFuture<WebserverHandle>

Starts a web server for a node
