Example 1 with Checksum

use of com.ms.silverking.cloud.dht.client.impl.Checksum in project SilverKing by Morgan-Stanley.

the class ValueUtil method verifyChecksum.

public static void verifyChecksum(byte[] storedValue, int storedOffset, byte[] value, int valueOffset, int valueLength) throws CorruptValueException {
    byte[] expectedChecksum;

    if (debugChecksum) {

    }
    checksumType = MetaDataUtil.getChecksumType(storedValue, storedOffset);
    if (checksumType != ChecksumType.NONE) {
        actualChecksum = MetaDataUtil.getChecksum(storedValue, storedOffset);
        checksum = ChecksumProvider.getChecksum(checksumType);
