write (byte[] b) 大字节数组的优化用法 [英] write (byte[] b) optim usage for large byte array

问题描述

如果内存中已经有一个从 SOAP 响应接收到的大字节数组.

If I have a large byte array already in memory received from a SOAP response.

我必须将这个字节数组写入一个 OutputStream.

I have to write this byte array into an OutputStream.

使用 write 就可以了:

It is OK just to use write:

byte [] largeByteArray=...;

outputstream.write(largeByteArray);

...
outputstream.flush();
...

还是更好地将字节数组拆分小块并将其写入输出流?

or is better to split the bytearray in small chunks and to write that to the outputstream?

推荐答案

如果你已经得到大数组，那么只需将它写出来——如果输出流实现选择将它分块，它可以做出这个决定.我看不出你这样做有什么好处 - 如果它能够处理大块，这很可能会降低效率.

If you've already got the large array, then just write it out - if the output stream implementation chooses to chunk it, it can make that decision. I can't see a benefit in you doing that for it - which may well make it less efficient, if it's able to handle large chunks.
