在面向字节的流中使用 ReadableByteStreamController 和使用 ReadableStreamBYOBReader 时,readableByteStreamController.byobRequest 属性提供对表示当前读取请求的 ReadableStreamBYOBRequest 实例的访问。该对象用于获取为读取请求填充而提供的 ArrayBuffer/TypedArray 的访问权限,并提供用于触发数据已提供信号的方法。
\When using ReadableByteStreamController in byte-oriented
streams, and when using the ReadableStreamBYOBReader,
the readableByteStreamController.byobRequest property
provides access to a ReadableStreamBYOBRequest instance
that represents the current read request. The object
is used to gain access to the ArrayBuffer/TypedArray
that has been provided for the read request to fill,
and provides methods for signaling that the data has
been provided.
