Class CheckSum

  • public final class CheckSum
    extends Object
    CheckSums are used by liquibase to determine if a Change has been modified since it was originally ran. CheckSums can be computed on either a String or an InputStream. The CheckSum contains a version number which can be used to determine whether the algorithm for computing a storedCheckSum has changed since the last time it was computed. If the algorithm changes, we cannot rely on the storedCheckSum value.

    It is not up to this class to determine what should be storedCheckSum-ed, it simply hashes what is passed to it.
