Examples of org.apache.vinci.transport.VinciFrame

org.apache.vinci.transport.VinciFrame
This is the "default" document class for use with the Vinci client and servable classes. VinciFrame implements a queryable frame from (nested) ArrayList data structures. Search time for a named tag is O(n) in the number of keys at a given depth, which is fine for all but the largest documents. VinciFrame complements the QueryableFrame adders and getters with several setter methods [fset(String, *)] for modifying the values of designated tags.


  // Equivalent to toFrame()
  // Need to check out the sources for this method


  public Frame toFrame() {
    Frame F = new VinciFrame(); // hack around the fact that Frame is an abstract class


    Object[] keys = dict.keySet().toArray();
    String S;
    Object O;


    for (int i = 0; i < keys.length; i++) {
      S = (String) keys[i];


      O = dict.get(S);
      // if (Frame.isFrame(O))
      if (1 == 0) // hack to get it to compile - can't find the isFrame() method
        F.fadd(S, (Frame) O);
      else
        F.fadd(S, O.toString());
    }


    return F;
  }
