Synopsis

This class is a utility class for CountedConstPtr and CountedPtr . It stores the reference count and the pointer to the real data.

Tip: It is currently a template and is used such that t is the true type of the stored pointer; This means, however, that when it is used, a template instantiation must be done for each type which t assumes; This makes debugging easier, but in the future all of these pointers could be declared with void type to avoid template instantiations;

Motivation

This class isolates all of the low level management of the reference.

Constructor & Destructor Documentation

template<class t>

casa::PtrRep< t >::PtrRep

(

t *

v

)

[inline, protected]

This constructor sets up the reference count to one and initializes the pointer to the real data.

The delit flag can be passed in to indicate whether the real data should be freed or not when the reference count reaches zero.
