class BufWriter

implements Writer

extends AbstractBufBase

import { BufWriter } from "https://dotland.deno.dev/std@0.119.0/io/mod.ts";

BufWriter implements buffering for an deno.Writer object. If an error occurs writing to a Writer, no more data will be accepted and all subsequent writes, and flush(), will return the error. After all data has been written, the client should call the flush() method to guarantee all data has been forwarded to the underlying deno.Writer.

Constructors

new

BufWriter(writer: Writer, size?: number)

Methods

flush()

Flush writes any buffered data to the underlying io.Writer.

reset(w: Writer): void

Discards any unflushed buffered data, clears any error, and resets buffer to write its output to w.

write(data: Uint8Array): Promise<number>

Writes the contents of data into the buffer. If the contents won't fully fit into the buffer, those bytes that can are copied into the buffer, the buffer is the flushed to the writer and the remaining bytes are copied into the now empty buffer.

Static Methods

create(writer: Writer, size?: number): BufWriter

return new BufWriter unless writer is BufWriter
