C++ (Cpp) calc_fee_visitor Examples

Example #1

File: fee_schedule.cpp Project: sfinder/graphene

 asset fee_schedule::calculate_fee( const operation& op, const price& core_exchange_rate )const
 {
    //idump( (op)(core_exchange_rate) );

    auto base_value = op.visit( calc_fee_visitor( params ) );
    auto scaled = fc::uint128(base_value) * scale;
    scaled /= GRAPHENE_100_PERCENT;
    FC_ASSERT( scaled <= GRAPHENE_MAX_SHARE_SUPPLY );
    auto result = asset( scaled.to_uint64(), 0 ) * core_exchange_rate;
    FC_ASSERT( result.amount <= GRAPHENE_MAX_SHARE_SUPPLY );
    return result;
 }
