Description

The list of methods to do CRC32 Byte Array are organized into topic(s).

Method

longcomputeCRC(byte[] value)
Returns the CRC value for the given byte[] 
CRC32 checksumEngine = new CRC32();
checksumEngine.update(value, 0, value.length);
long checksumMessage = checksumEngine.getValue();
checksumEngine.reset();
return checksumMessage;
longcomputeCRC32(byte[] bytes)
compute CRC 
CRC32 crc = new CRC32();
crc.reset();
crc.update(bytes);
return crc.getValue();
intcrc32(byte[] array)
crc 
if (array != null) {
    return crc32(array, 0, array.length);
return 0;
longcrc32(byte[] bts)
Calculates the crc32 and casts it to an integer, this avoids clojure's number autoboxing 
final CRC32 crc = new CRC32();
crc.update(bts);
return crc.getValue();
intCRC32(byte[] buffer)
CRC 
CRC32 crc = new CRC32();
crc.update(buffer);
return (int) crc.getValue();
longcrc32(byte[] bytes)
Compute the CRC32 of the byte array 
return crc32(bytes, 0, bytes.length);
Stringcrc32(byte[] bytes)
crc 
java.util.zip.CRC32 x = new java.util.zip.CRC32();
x.update(bytes);
String crcString = Long.toHexString(x.getValue());
if (crcString.length() % 2 != 0) {
    crcString = "0" + crcString;
String reverseCrcString = crcString.substring(6, 8) + crcString.substring(4, 6) + crcString.substring(2, 4)
        + crcString.substring(0, 2);
...
longcrc32(final byte[] bytes)
crc 
Checksum checksum = new CRC32();
checksum.update(bytes, 0, bytes.length);
long checksumValue = checksum.getValue();
return checksumValue;
intcrc32(String value)
Computes and returns the CRC32 hash value for the supplied string. 
_crc.reset();
_crc.update(value.getBytes());
return (int) _crc.getValue();
longcrc32Number(String s)
crc Number 
try {
    byte bytes[] = s.getBytes();
    Checksum checksum = new CRC32();
    checksum.update(bytes, 0, bytes.length);
    long lngChecksum = checksum.getValue();
    return lngChecksum;
} catch (Exception e) {
    e.printStackTrace();
