"this" keyword in OOP
 

Hello
In many OOP languages "this"(or something similar) is used to point to current object. But i think its an object by itself. Here is what i found" polymorphic object which can point in different times to different object`s types"
I like to get some more information about this maybe some science article.
Thank you in advance.

What more information could there possibly be??? As you already stated its just a pointer to the current c++ class object.

For example, here's the output of the following in c++. It shows that the this pointer is the same in both child and parent.

A:  this = 2afc38

B:  this = 2afc38

Press any key to continue . . .

class A

{

public:

    A() 

    {

        x = 0;

    cout << "A:  this = " << hex << (unsigned int)this << "\n";

    }

private:

    int x;

};



class B : public A

{

public:

    B()

    {

        y = 0;

        cout << "B:  this = " << hex << (unsigned int)this << "\n";

    }

private:

    int y;

};





int main(int argc, char* argv[])

{

    B b;

}

Its just a Compilers way of saying "The main object under my concern right now is this" ,as AncientDragon has stated its just a pointer which is maintained completely by compiler which the user cannot modify,but can make use of it foir referencing the current object.For more info try these 1 2.

In Java you can think of 'this' as being the same thing as the name of the Object. So if you are in the class MyClass, 'this' is your MyClass Object.
