universalCall from class fcf::SpecifierInfo

Property: universalCall

Type: fcf::UniversalCall

Class: fcf::SpecifierInfo

Package: fcfBasis

File: bits/PartSpecifier/SpecifierInfo.hpp

Available from version: 1.0.1

Universal call function wrapper that performs the action of the specifier.

Provides a standardized interface for invoking the operator through the framework's universal calling mechanism.

Example:

#include <iostream> // Define an implementation macro to include the implementation section in header files #define FCF_BASIS_IMPLEMENTATION #include <fcfBasis/basis.hpp> int main() { const fcf::TypeInfo* ti = fcf::Type<int>().typeInfo(); unsigned int lessSpecifierTypeId = fcf::Type<fcf::LessSpecifier>().index(); const fcf::SpecifierInfo& si = ti->specifiers.find(lessSpecifierTypeId)->second; fcf::UniversalCall universalCall = si.universalCall; int left = 1; int right = 2; fcf::Variant rightWrapper(right, fcf::Variant::REFERENCE); fcf::Variant lessValue = universalCall(&left, &rightWrapper, 1); std::cout << "1 < 2: " << lessValue << std::endl; return 0; }

Output:

1 < 2: true
