chunkReadCount: number

chunkWrittenCount

chunkWrittenCount: number

name

name: string

default

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.

Accessors

isDisconnecting

  • get isDisconnecting(): boolean

  • Returns boolean

timeout

  • get timeout(): number
  • set timeout(value: number): any

  • Returns number

  • Parameters

    • value: number

    Returns any

Methods

addListener

  • addListener(event: string | symbol, listener: (...args: any[]) => void): TCP_transport

  • Parameters

    • event: string | symbol
    • listener: (...args: any[]) => void
        • (...args: any[]): void

        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns TCP_transport

createChunk

  • createChunk(msgType: string, chunkType: string, length: number): Buffer

  • createChunk is used to construct a pre-allocated chunk to store up to length bytes of data. The created chunk includes a prepended header for chunk_type of size self.headerSize.

    method

    createChunk

    Parameters

    • msgType: string
    • chunkType: string

      chunk type. should be 'F' 'C' or 'A'

    • length: number

    Returns Buffer

    a buffer object with the required length representing the chunk.

    Note:

    • only one chunk can be created at a time.
    • a created chunk should be committed using the write method before an other one is created.

disconnect

  • disconnect the TCP layer and close the underlying socket. The "close" event will be emitted to the observers with err=null.

    method
