Class CRC64Checksum

  • All Implemented Interfaces:
    Checksum

    public class CRC64Checksum
    extends Object
    implements Checksum
    Utility class that calculates a CRC64 checksum on a stream of bytes. Code was based on some from BioPerl. Note that we use longs then cast them to avoid the lack of an unsigned int in Java. Longs are 64-bit but we are only using the bottom 32 bits. An int is 32-bit but encodes sign so we can get amusing results if we don't allow for this.
