The unpack() method is the counterpart to the pack() method. It receives a
container as a parameter and restores the type specific variables of the class. The
method returns a Boolean with the value true if the information could be restored.
The unpack() method handles the current version number as a minimum, which
is defined in the ClassDeclaration. You can select to support unpacking of older
versions by extending the switch statement.
The unpack() method has the following content.

public boolean unpack(container _packedClass)
{
  Version version = 
  RunBase::getVersion(_packedClass);
  switch (version)
  {
    case(#CurrentVersion) :
    [version,#CurrentList] = _packedClass;
    break;
    default :
    return false;
  }
  return true;
}
