的具体用法。这些代码示例主要来源于Github

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。HashCode.padToLong()
方法的具体详情如下:
包路径:com.google.common.hash.HashCode
类名称:HashCode
方法名:padToLong
[英]If this hashcode has enough bits, returns asLong(), otherwise returns a longvalue with asBytes() as the least-significant bytes and 0x00 as the remaining most-significant bytes.
[中]如果此哈希代码有足够的位,则返回asLong(),否则返回一个longvalue,其中asBytes()为最低有效字节,0x00为剩余最高有效字节。

return consistentHash(hashCode.padToLong(), buckets);

HashCode md5 = Files.hash(file, Hashing.md5());
byte[] md5Bytes = md5.asBytes();
String md5Hex = md5.toString();
HashCode crc32 = Files.hash(file, Hashing.crc32());
int crc32Int = crc32.asInt();
// the Checksum API returns a long, but it's padded with 0s for 32-bit CRC
// this is the value you would get if using that API directly
long checksumResult = crc32.padToLong();
