getChecksumBytes

public byte[] getChecksumBytes()

Description copied from interface: SdkChecksum

Returns the computed checksum in a byte array rather than the long provided by Checksum.getValue().

Specified by:

getChecksumBytes in interface SdkChecksum

Returns:

byte[] containing the checksum

mark

public void mark(int readLimit)

Description copied from interface: SdkChecksum

Allows marking a checksum for checksums that support the ability to mark and reset.

Specified by:

mark in interface SdkChecksum

Parameters:

readLimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
