// pointer from being initialized in the constructor and destructor for the
|
||
|
|
// class. This has many benefits because the linker can now eliminate the
|
||
|
|
// vtable and all the functions pointed to by the vtable. Also, the actual
|

|
// constructor and destructor code are now smaller.

///////////////////////////////////////////////////////////////////////////////

// rather only used as a base class. Additionally, the constructor and
|

// a virtual function call to occur back on the object.
