Interface Algorithm

All Known Implementing Classes:
ChecksumAlgorithm, DigestAlgorithm, HashvalueAlgorithm, LastModifiedAlgorithm
public interface Algorithm
The Algorithm defines how a value for a file is computed. It must be sure that multiple calls for the same file results in the same value. The implementing class should implement a useful toString() method.
