boost visitor

Boost.Variant is a library in the Boost library that helps boost visitor.

It allows for the creation of a single variable that can hold values of different types.

This is useful when dealing with polymorphic types or when the type of a value may change during the runtime of an application.

With Boost.Variant, we can define a boost::variant variable that can store values of different types.

We can then use the boost::get() function template to retrieve the stored values in a type-safe manner.

To perform different operations based on the type of the stored value, we can use boost::apply_visitor().

This function performs type-safe access to the stored values by using an overloaded operator() in a derived class.

This allows us to simplify our code and automatically call the appropriate overloaded function based on the type of the stored value.

By using Boost.Variant, we can boost visitor and avoid runtime errors and simplify our code compilation.

Key Points:

  • Boost.Variant is a library within the Boost library that assists in boosting visitor.
  • It enables the creation of a single variable capable of holding different types of values.
  • Useful when working with polymorphic types or when the value’s type may change during runtime.
