-namespace sandbox {
-
-// Models the set of interesting parameters of an intercepted system call
-// normally you don't create objects of this class directly, instead you
-// use the POLPARAMS_XXX macros.
-// For example, if an intercepted function has the following signature:
-//
-// NTSTATUS NtOpenFileFunction (PHANDLE FileHandle,
-//                              ACCESS_MASK DesiredAccess,
-//                              POBJECT_ATTRIBUTES ObjectAttributes,
-//                              PIO_STATUS_BLOCK IoStatusBlock,
-//                              ULONG ShareAccess,
-//                              ULONG OpenOptions);
-//
-// You could say that the following parameters are of interest to policy:
-//
-//   POLPARAMS_BEGIN(open_params)
-//      POLPARAM(DESIRED_ACCESS)
-//      POLPARAM(OBJECT_NAME)
-//      POLPARAM(SECURITY_DESCRIPTOR)
-//      POLPARAM(IO_STATUS)
-//      POLPARAM(OPEN_OPTIONS)
-//   POLPARAMS_END;
-//
-// and the actual code will use this for defining the parameters:
-//
-//   CountedParameterSet<open_params> p;
-//   p[open_params::DESIRED_ACCESS] = ParamPickerMake(DesiredAccess);
-//   p[open_params::OBJECT_NAME] =
-//       ParamPickerMake(ObjectAttributes->ObjectName);
-//   p[open_params::SECURITY_DESCRIPTOR] =
-//       ParamPickerMake(ObjectAttributes->SecurityDescriptor);
-//   p[open_params::IO_STATUS] = ParamPickerMake(IoStatusBlock);
-//   p[open_params::OPEN_OPTIONS] = ParamPickerMake(OpenOptions);
-//
-//  These will create an stack-allocated array of ParameterSet objects which
-//  have each 1) the address of the parameter 2) a numeric id that encodes the
-//  original C++ type. This allows the policy to treat any set of supported
-//  argument types uniformily and with some type safety.
-//
-//  TODO(cpu): support not fully implemented yet for unicode string and will
-//  probably add other types as well.
