ReadableByteStreamController.constructor

Draft
This page is not complete.

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The ReadableByteStreamController() constructor creates and returns a ReadableByteStreamController() object instance.

Note: You wouldn't use this constructor manually — this is used during the construction of a ReadableStream object.

Syntax

var readableStreamController = new ReadableStreamController(stream, underlyingSource, highWaterMark);

Parameters

stream
The ReadableStream to be controlled.
underlyingSource
An object containing methods and properties that define how the constructed stream instance will behave. See the ReadableStream() constructor's parameters definitions for more information.
highWaterMark
A non-negative integer — this defines the total number of chunks that can be contained in the internal queue before backpressure is applied.

Return value

An instance of the ReadableByteStreamController object.

Exceptions

RangeError
The associated ReadableStream was constructed with autoAllocateChunkSize set, but its value is not an integer or below 0.
TypeError
The supplied stream parameter is not a ReadableStream, or it already has an associated controller.

Examples

TBD
