This class generates random language elements for a parser and tests that the parser can accept them.
author:

version:
   1.0



Field Summary
protected  booleanlogTestStrings
    
protected  Parserp
    

Constructor Summary
public  ParserTester(Parser p)
     Constructs a tester for the given parser.

Method Summary
abstract protected  Assemblyassembly(String s)
     Subclasses must override this, to produce an assembly from the given (random) string.
protected  booleancanGenerateProblem(int depth)
     Generate a random language element, and return true if the parser cannot unambiguously parse it.
public static  ListcompleteMatches(List in)
     Return a subset of the supplied vector of assemblies, filtering for assemblies that have been completely matched.
protected  PubliclyCloneablefreshTarget()
     Give subclasses a chance to provide fresh target at the beginning of a parse.
protected  voidlogDepthChange(int depth)
     This method is broken out to allow subclasses to create less verbose tester, or to direct logging to somewhere other than System.out.
protected  voidlogPassed()
     This method is broken out to allow subclasses to create less verbose tester, or to direct logging to somewhere other than System.out.
protected  voidlogProblemFound(String s, int matchSize)
     This method is broken out to allow subclasses to create less verbose tester, or to direct logging to somewhere other than System.out.
protected  voidlogTestString(String s)
     This method is broken out to allow subclasses to create less verbose tester, or to direct logging to somewhere other than System.out.
protected  Stringseparator()
     By default, place a blank between randomly generated "words" of a language.
public  voidsetLogTestStrings(boolean logTestStrings)
     Set the boolean which determines if this class displays every test string.
public  voidtest()
     Create a series of random language elements, and test that the parser can unambiguously parse each one.
