public class TestAat  {
// Copyleft Harvey Greenberg, UW hgreen@u.washington.edu
// This calls Aat to load an ARC/INFO AAT file into an array of objects,
// processes them, and writes a report.
// The first argument is the name of an arc cover.
// The second argument is the name of a data item, such as ELEV.
// This can be called from the command line: e.g. java TestAat con300 ELEV
// or from another class, such as CheckMany.java.
// This program checks each arc to make certain that the given item matches
// on connected arcs.
// Exceptions are written to standard error.
// Caveats:
//  Error handling is neither complete nor elegant
//  This class and class Arccheck assume a unix style "/" separator, which is
//  probably not portable.
//  This will not recognize AAT files which are not stored as "aat.adf".
//  Class Arccheck assumes a specific item list for the arcs being checked. 
//  Although this is very fast on small files, it uses an n-squared search,
//  and is slower on larger files.
//  A commented-out block of code for writing to the AAT is included only for
//  your edification.
//  This was compiled and checked under JDK Beta3 under Solaris.
