What does the pointer 'this+1' refer to in C++?

Question

I was wandering through the code of Sequitur G2P and found a really strange line of code:

public:
    ...
    const Node *childrenEnd() const { return (this+1)->finalized.firstChild_; }

I know that this is a pointer to the current object, and since it is a pointer, the operation is perfectly legal, but what does this+1 actually refer to?

Answer 1

Presumably this is part of an array, so this+1 would refer to the next object in that array.
