Do not use the this. construction to dereference members. The use of this is only allowed as a reference to the current class instance or to prevent name clashing between method parameters and class members.

A member function shall not use the this keyword to access a data member of member function:

void
Example::foo()
{
  this->bar();    // wrong
  (*this).bar();  // wrong
  bar();          // right

  this->data = 0; // wrong
  data = 0;       // right
}
