  +--admin.RequirementParser

public class RequirementParser

extends java.lang.Object

In the add modify module, the requirement strings the user builds are not in the native format stored in the SAS database. This class acts as the bridge between the two formats, allowing convienient conversion between the two formats. The format used in the database is referred to as database format, and the format used in displaying the requirement to the user is referred to as display format. Database format looks something like "1|(4#5)|^06" and display format looks something like "CSC 175N or ( MTH 072A xor MTH 073A ) or all PHY".
