CWTemp

template < class C > class CWTemp

Copy on write data vector class template.

Public Fields
typedef unsigned int size_t: General purpose data length type
typedef C container_t: Underlying container type
typedef pair <size_t, container_t> node_t: Node containing the use count and a data container
typedef typename C::iterator iterator: Iterator borrowed from the container
typedef typename C::const_iterator const_iterator: Constant iterator borrowed from container
typedef typename C::value_type value_type: Data type borrowed from container

Documentation

The CWTemp template classes allow data in a specified container to be shared by more than one Data vector without forcing a copy. This is especially useful for reducing overheads when passing ownership of long data vectors. A data vector can be copied using the assignment (=) operator, and the data container is referenced with the getRef method.
