Constructors

constructor

+ new Sender(): Sender

Overrides void

Defined in lib/net/protocol/sender.ts:12

Returns: Sender

Properties

Static defaultMaxListeners

▪ defaultMaxListeners: number

Inherited from Sender.defaultMaxListeners

Defined in node_modules/@types/node/events.d.ts:45

---

Static errorMonitor

▪ errorMonitor: keyof symbol

Inherited from Sender.errorMonitor

Defined in node_modules/@types/node/events.d.ts:55

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.
