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.

    return getFrame(ok, "Delete Service request failed");

  VinciFrame delAlias(VinciFrame in) {
    logRequest(dirCmdDelAlias, in.fgetString("vinci:REMOTEIP"), null);
    VinciFrame service = in.fgetVinciFrame("SERVICE");
    boolean ok = true;
    if (service.fgetString("NAME") == null || service.fgetString("TARGET") == null) {
      getFrame(false, "Malformed request");
    } else {
      synchronized (SR) {
        ok = SR.delAlias(service.fgetString("NAME"));
      }
    }
    return getFrame(ok, "Delete alias request failed");
