Attached are two that work using the "set()" function.


As a third choice:

You could also create a new constructor that actually takes an int64_t bitmap, and use

GetLayerMask() to build it.

However I would rename GetLayerMask() to something more concise:


const LAYER_SET LAYER_SET::IMPORTANT_SET = LMSK( LAYER_CU_FRONT ) | LMSK( LAYER_CU_BACK );


So there, now you have 3 choices.  This, plus the attached.

P.S. I sort of LAYER_SET better than LAYER_MSK as a type name.




#include <stdio.h>
#include <stdint.h>

//#define __STDC_FORMAT_MACROS

#include <inttypes.h>
#include <vector>


#include <bitset>

enum LAYER_NUM
{
    LAYER_CU_FRONT,
    LAYER_CU_BACK,
};


#if 0

typedef std::bitset<64>     LAYER_SET;

const LAYER_SET CU_EXTERNAL = LAYER_SET().set( LAYER_CU_FRONT ).set( LAYER_CU_BACK );

int main( int argc, char** argv )
{
    printf( "value %" PRIu64 "\n", *(int64_t*) &CU_EXTERNAL );

    return 0;
}

#else

typedef std::bitset<64> BASE_SET;

class LAYER_SET : public BASE_SET
{
public:
    static const LAYER_SET   CU_EXTERNAL;

    LAYER_SET( const LAYER_SET& other )
    {
        *this = other;
    }

    LAYER_SET() : BASE_SET() {}

    LAYER_SET& set( int index )
    {
        return (LAYER_SET&) BASE_SET::set( index );
    }
};

const LAYER_SET LAYER_SET::CU_EXTERNAL = LAYER_SET().set( LAYER_CU_FRONT ).set( LAYER_CU_BACK );

int main( int argc, char** argv )
{
    printf( "value %" PRIu64 "\n", *(int64_t*) &LAYER_SET::CU_EXTERNAL );

    return 0;
}
