Method Summary

(package private) abstract void	editData(java.util.List<Student> roster, Student student, Grade input) Allows users to enter data into fields and ensures the number is within a reasonable range and that the student exists /*@ requires roster.contains(student); ensures input.grade < 400 && input.grade > -100);
(package private) abstract void	setCurve(java.util.List<java.lang.Double> cutoffs) Allows users to set a curve and ensures it is a number between 0 and 100
(package private) abstract java.util.Collection<Student>	sortBy(int col, java.util.List<Student> students) Ensures the gradebook is sorted according to a rule and that the column is valid
(package private) abstract boolean	sortedAscending(java.util.List<Student> students, int col) Return true if the given list is sorted in ascending order
(package private) abstract boolean	sortedByName(java.util.List<Student> students) Return true if the given list is sorted lexicographically by name, according to the semantics * of java.lang.String.compareTo().
(package private) abstract boolean	sortedByRevName(java.util.List<Student> students) Return true if the given list is sorted lexicographically by name, according to the semantics * of java.lang.String.compareTo().
