本文整理了Java中io.airlift.slice.Slice.setByte()方法的一些代码示例，展示了Slice.setByte()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Slice.setByte()方法的具体详情如下：
包路径：io.airlift.slice.Slice
类名称：Slice
方法名：setByte

Slice.setByte介绍

[英]Sets the specified byte at the specified absolute index in this buffer. The 24 high-order bits of the specified value are ignored.
[中]在该缓冲区中指定的绝对索引处设置指定字节。指定值的24个高位将被忽略。

private static void verifySlice()
{
  Slice slice = Slices.wrappedBuffer(new byte[5]);
  slice.setByte(4, 0xDE);
  slice.setByte(3, 0xAD);
  slice.setByte(2, 0xBE);
  slice.setByte(1, 0xEF);
  if (slice.getInt(1) != 0xDEADBEEF) {
    failRequirement("Slice library produced an unexpected result");
  }
}

代码示例来源：origin: prestodb/presto

public static Slice padSpaces(Slice slice, int length)
{
  int textLength = countCodePoints(slice);
  // if our string is bigger than requested then truncate
  if (textLength > length) {
    throw new IllegalArgumentException("pad length is smaller than slice length");
  }
  // if our target length is the same as our string then return our string
  if (textLength == length) {
    return slice;
  }
  // preallocate the result
  int bufferSize = slice.length() + length - textLength;
  Slice buffer = Slices.allocate(bufferSize);
  // fill in the existing string
  buffer.setBytes(0, slice);
  // fill padding spaces
  for (int i = slice.length(); i < bufferSize; ++i) {
    buffer.setByte(i, ' ');
  }
  return buffer;
}
