Class Result

  org.jatha.dynatype.StandardLispValue
      org.algernon.datatype.Result

All Implemented Interfaces:

Comparable, LispValue

public class Result

extends StandardLispValue

This class contains a result from an Algernon ask or tell operation. Use the iterator to step through the binding lists in the result. To parse a result, use this code

   LispValue result = algy.ask("...");

   if (result == null)
     ...
   else
   {
     for (Iterator iterator = ((Result)result).iterator(); iterator.hasNext();)
     {
       BindingList bl = (BindingList) iterator.next();
       Object value = algy.getBinding("?x", bl);

       // Object will either be a Java Object (Integer, Float, etc.)
       // or a KB object (typically a Protege Instance).
       // If you want Algernon objects, use getAlgernonBinding().
     }
   }

Constructor Detail

Result

public Result(Algernon algy,
              LispValue valuesAndBindingSets)

Method Detail

getResultVariables

public LispValue getResultVariables()

Returns a LISP list of the variables in the Result. Each binding list should have the same set of variables, so we only look at the first one. The returned list is alphabetized. Returns NIL if there are no variables.

iterator

public Iterator iterator()

Each element of the iteration is a BindingList.

size

public int size()

Returns the number of results in the Result.

toString

public String toString()

Returns a printed representation
