Node.js Buffer.buffer 属性
Buffer.buffer属性是buffer模块中Buffer类的内置应用程序接口,用于获取与该buffer对象等价的数组buffer对象。
句法:
const buf.buffer
返回值:该属性返回数组缓冲区的对象。
示例 1:文件名:index.js
Javascript
// Node.js program to demonstrate the
// Buffer.buffer property
// Creating a Buffer
const buff = Buffer.from([1, 2, 3, 4, 5]);
// Getting the value of array buffer
const value = buff.buffer;
// Display the result
console.log("Big Integer :- " + value);
Javascript
// Node.js program to demonstrate the
// Buffer.buffer property
// Creating and initializing arraybuffer object
const arrbuff = new ArrayBuffer(16);
// Getting buffer object form existing
// arraybuffer object
const buffer = Buffer.from(arrbuff);
// Display the result
if(buffer.buffer === arrbuff)
console.log("both buffer is equivalent");
else
console.log("both buffer is not equivalent");
输出:
Big Integer :- [object ArrayBuffer]
示例 2:文件名:index.js
Javascript
// Node.js program to demonstrate the
// Buffer.buffer property
// Creating and initializing arraybuffer object
const arrbuff = new ArrayBuffer(16);
// Getting buffer object form existing
// arraybuffer object
const buffer = Buffer.from(arrbuff);
// Display the result
if(buffer.buffer === arrbuff)
console.log("both buffer is equivalent");
else
console.log("both buffer is not equivalent");
输出:
both buffer is equivalent
使用以下命令运行index.js 文件:
node index.js
