示例1: greater

/// \brief Test whether that is greater than this type
bool ASTType::greater(const ASTType& that) const
{
   if ( isNull() && (that.isObject() || that.isArray() || that.isString() || that.isGeneric()) )
   {
      return true;
   }
   else if ( isObject() && that.isObject() )
   {
      // check if 'that' is a extending or implemented this

      if ( !(mTypeArguments == that.mTypeArguments) )
      {
         return false;
      }

      return getObjectClass().isBase(that.getObjectClass()) 
          || getObjectClass().isImplementing(that.getObjectClass());
   }
   else if ( isArray() && that.isArray() )

   }
   else if ( isGeneric() )
   {
