Buffer.compare(buf1, buf2)
buf1
<Buffer> | <Uint8Array>buf2
<Buffer> | <Uint8Array>- 返回: <integer>
-1
、0
或1
,取决于比较的结果。 详见buf.compare()
。
比较 buf1
和 buf2
,通常用于对 Buffer
实例的数组进行排序。
这相当于调用 buf1.compare(buf2)
。
const buf1 = Buffer.from('1234');
const buf2 = Buffer.from('0123');
const arr = [buf1, buf2];
console.log(arr.sort(Buffer.compare));
// 打印: [ <Buffer 30 31 32 33>, <Buffer 31 32 33 34> ]
// (此结果相当于:[buf2, buf1]。)
buf1
<Buffer> | <Uint8Array>buf2
<Buffer> | <Uint8Array>- Returns: <integer> Either
-1
,0
, or1
, depending on the result of the comparison. Seebuf.compare()
for details.
Compares buf1
to buf2
, typically for the purpose of sorting arrays of
Buffer
instances. This is equivalent to calling
buf1.compare(buf2)
.
const buf1 = Buffer.from('1234');
const buf2 = Buffer.from('0123');
const arr = [buf1, buf2];
console.log(arr.sort(Buffer.compare));
// Prints: [ <Buffer 30 31 32 33>, <Buffer 31 32 33 34> ]
// (This result is equal to: [buf2, buf1].)
