Template Method

Общая реализация на языке С++

AbstractClass

class AbstractClass
{
public:
    void templateMethod()
    {
        primitiveOperation();
        concreteOperation();
        hook();
    }
    virtual ~AbstractClass() = default;
protected:
    virtual void primitiveOperation() = 0;
    void concreteOperation() 
    { 
        cout << "concreteOperation;" << endl; 
    }
    virtual void hook() 
    { 
        cout << "hook Base;" << endl; 
    }
};

ConcreteClassA

class ConcreteClassA : public AbstractClass
{
protected:
    void primitiveOperation() override 
    { 
        cout << "primitiveOperation A;" << endl; 
    }
};

ConcreteClassB

class ConcreteClassB : public AbstractClass
{
protected:
    void primitiveOperation() override 
    { 
        cout << "primitiveOperation B;" << endl; 
    }
    void hook() override 
    { 
        cout << "hook B;" << endl; 
    }
};

#include <iostream>

using namespace std;

int main()
{
    ConcreteClassA ca;
    ConcreteClassB cb;

    ca.templateMethod();
    cb.templateMethod();
}
