BOOST_PP_ENUM_SHIFTED_PARAMS

The BOOST_PP_ENUM_SHIFTED_PARAMS macro generates a comma-separated, shifted list of parameters.

#### Usage

BOOST_PP_ENUM_SHIFTED_PARAMS(count, param)

#### Arguments

count
  The number of parameters to generate. Valid values range from 0 to BOOST_PP_LIMIT_REPEAT.
param
  The text of the parameter. BOOST_PP_ENUM_SHIFTED_PARAMS concatenates numbers ranging from 1 to count - 1 to generate parameters.

#### Remarks

This macro expands to the comma-separated sequence:
param ## 1, ... param ## count - 1
This macro facilitates a typical usage of the library. Shifted parameter lists are common in template metaprograms.
To use the z parameter passed from other macros that use BOOST_PP_REPEAT, see BOOST_PP_ENUM_SHIFTED_PARAMS_Z.
Previously, this macro could not be used recursively inside BOOST_PP_REPEAT. This limitation no longer exists, as the library can automatically detect the next available repetition depth.

#### See Also

- BOOST_PP_LIMIT_REPEAT
- BOOST_PP_SHIFTED_ENUM_PARAMS_z

#### Requirements

Header: <boost/preprocessor/repetition/enum_shifted_params.hpp>

#### Sample Code

    #include <boost/preprocessor/repetition/enum_shifted_params.hpp>

    BOOST_PP_ENUM_SHIFTED_PARAMS(3, class T) // expands to class T1, class T2
