包路径：com.netflix.hollow.core.memory.encoding.ZigZag
类名称：ZigZag

ZigZag介绍

[英]Zig-zag encoding. Used to encode FieldType#INT and FieldType#LONG because smaller absolute values can be encoded using fewer bits.
[中]Z字形编码。用于对FieldType#INT和FieldType#LONG进行编码，因为较小的绝对值可以使用较少的位进行编码。

代码示例

return data.get(location) == 1;
case INT:
  return ZigZag.decodeInt(VarInt.readVInt(data, location));
case LONG:
  return ZigZag.decodeLong(VarInt.readVLong(data, location));
case DOUBLE:
  long longBits = data.readLongBits(location);
