Regular referenced counted pointer for non-constant data.
Public interface
This class completes the lattice. It inherits much of the members which deal with non-constant data from SimpleCountedPtr , and it inherits the const operator->() from CountedConstPtr . What this class adds is the operator->() which returns a modifiable pointer.

| casa::CountedPtr< t >::CountedPtr | ( | ) |
This constructor allows for the creation of a null CountedPtr.
The assignment operator can be used to assign a null CountedPtr from another pointer.
| casa::CountedPtr< t >::CountedPtr | ( | t * | val, | |
| Bool | delit = True | |||
| ) |
This constructor sets up a reference count for the val pointer.
By default, the data pointed to by val will be deleted when it is no longer referenced. Passing in False for delit will prevent the data from being deleted when the reference count reaches zero.
Warning: After the counted pointer is initialized the value should no longer be manipulated by the raw pointer of type t*;
| casa::CountedPtr< t >::CountedPtr | ( | const CountedPtr< t > & | val | ) |
This copy constructor allows CountedPtrs to be initialized from other CountedPtrs.
| t* casa::CountedPtr< t >::operator-> | ( | ) | const [inline] |
This dereferencing operator behaves as expected; it returns the pointer to the value being protected, and then its dereferencing operator will be invoked as appropriate.
If the pointer is un-initialized (null), an exception will be thrown. The member function null () can be used to catch such a condition in time.
