Public Member Functions | |
| array_autoptr (T *p=0) | |
| Creates a new array_autoptr and optionally initialises it with the specified pointer, taking ownership of array of objects pointed to by it. | |
| array_autoptr (const array_autoptr< T > &that) | |
| Copies the array_autoptr and takes ownership of the array the original pointed to. | |
| ~array_autoptr () | |
| Destroys the array_autoptr and calls delete [] on the array pointed to. | |
| T * | release () |
| Returns a pointer to the owned array, relinquishing ownership of the pointed to array. | |
| T * | get () |
| Returns a pointer to the owned array, but does not relinquish ownership. | |

boost::scoped_array may not be suitable because it is noncopyable and doesn't have a release method. boost::shared_array is overkill. Use of std::vector and std::auto_ptr is recommended in many cases over a dynamically created array, but sometimes this is a better idea. jsplib::array_autoptr is useful when implementing exception safety - create at start of function and release at the end after anything to throw.
| jsplib::array_autoptr< T >::array_autoptr | ( | const array_autoptr< T > & | that | ) | [inline] |
Copies the array_autoptr and takes ownership of the array the original pointed to.
post-conditon: The original is set to a null pointer
| T* jsplib::array_autoptr< T >::get | ( | ) | [inline] |
Returns a pointer to the owned array, but does not relinquish ownership.
On destruction of this object the array will still be deleted [] unless release is called before destruction
| T* jsplib::array_autoptr< T >::release | ( | ) | [inline] |
Returns a pointer to the owned array, relinquishing ownership of the pointed to array.
The array is not deleted [] on release and the array_autoptr is initialised to a null pointer
