Structured Matcher is part of the Object-Oriented Programming for Artificial Intelligence CSCI 322 class project to convert an A.I tool called GT into Java. If you are unfamiliar with structured matchers, a Postscript document is available to explain what it is. The package we are writing implements classes that represents structured matchers and their underlying simple matchers with View classes that allow the user to manipulate objects of simple and structured matchers. We are following the Model-View/Controller paradigm in OOP application programming for our package. This means that other programmers can integrate SM into their own software. The main classes that are the Models for the package are StructuredMatcher and SimpleMatcher. These classes implements the logic behind the operations of the structured matcher. To manipulate and view objects of these classes are the View classes of StructuredMatcherView and SimpleMatcherView. The other classes found in the package are support classes that implement the data types involved in the operation of a structured matcher.
