Hash

• string 32
• int 32
• long 32
• double 32
• string 64
• string 128

用于生成不同位数的哈希值。

string 32

String key = "test";
int seed = 123;
Hash.hash32(key.getBytes(), key.getBytes().length, seed);

int 32

byte[] data = ByteBuffer.allocate(4).putInt(1122).array();
Hash.hash32(data, data.length, seed);

long 32

byte[] data = ByteBuffer.allocate(8).putLong(3344L).array();
Hash.hash32(data, data.length, seed);

double 32

byte[] data = ByteBuffer.allocate(8).putDouble(3344D).array();
Hash.hash32(data, data.length, seed);

string 64

byte[] origin = "value".getBytes();
Hash.hash64(origin, 0, origin.length);

string 128

String key = "test";
int seed = 123;
Hash.hash128(key.getBytes(), 0, key.getBytes().length, seed);
