minimumSamplingInterval: number

Optional Readonly modellingRule

modellingRule: ModellingRuleType

Readonly namespace

namespace: Namespace

Readonly namespaceIndex

namespaceIndex: number

Readonly namespaceUri

namespaceUri: string

Readonly nodeClass

- Returns Promise<void>

Optional Readonly parentNodeId

parentNodeId: NodeId

Readonly subtypeOf

subtypeOf: NodeId

Readonly subtypeOfObj

subtypeOfObj: UAVariableType

valueRank

valueRank: number

Readonly Static captureRejectionSymbol

captureRejectionSymbol: typeof captureRejectionSymbol

Static captureRejections

captureRejections: boolean

Sets or gets the default captureRejection value for all emitters.

Static defaultMaxListeners

defaultMaxListeners: number

Readonly Static errorMonitor

errorMonitor: typeof errorMonitor

This symbol shall be used to install a listener for only monitoring 'error' events. Listeners installed using this symbol are called before the regular 'error' listeners are called.

Installing a listener using this symbol does not change the behavior once an 'error' event is emitted, therefore the process will still crash if no regular 'error' listener is installed.
