/**
 * This processor converts the input to a string, and enforces a requirement that the input's hash function returns any
 * of a given set of hashcodes (specified as one or one in a set of hash codes). Lookup time is O(1).
 * <p>
 * This constraint is a very efficient way of ensuring constant expressions are present in certain columns of the CSV
 * file, such as "BOSS", "EMPLOYEE", or when a column denote an action to be taken for the input line such as "D"
 * (delete), "I" (insert), ...
 * <P>
 * It corresponds to the {@link Required} class, but is renamed to the new name clearer conveying the semantics.
 *
