|
//! Originally developed by Joaquin M. Lopez Munoz, stable_vector is a std::vector
|
|
//! drop-in replacement implemented as a node container, offering iterator and reference
|
|
//! stability.
|
|
//!
|
|
//! Here are the details taken from the author's blog
|
|
//! (<a href="http://bannalia.blogspot.com/2008/09/introducing-stablevector.html" >
|
|
//! Introducing stable_vector</a>):
|
|
//!
|
|
//! We present stable_vector, a fully STL-compliant stable container that provides
|
|
//! most of the features of std::vector except element contiguity.
|
|
//!
|
|
//! General properties: stable_vector satisfies all the requirements of a container,
|
|
//! a reversible container and a sequence and provides all the optional operations
|
|
//! present in std::vector. Like std::vector, iterators are random access.
|
|
//! stable_vector does not provide element contiguity; in exchange for this absence,
|
|
//! the container is stable, i.e. references and iterators to an element of a stable_vector
|
|
//! remain valid as long as the element is not erased, and an iterator that has been
|
|
//! assigned the return value of end() always remain valid until the destruction of
|
|
//! the associated stable_vector.
|
|
//!
|
|
//! Operation complexity: The big-O complexities of stable_vector operations match
|
|
//! exactly those of std::vector. In general, insertion/deletion is constant time at
|
|
//! the end of the sequence and linear elsewhere. Unlike std::vector, stable_vector
|
|
//! does not internally perform any value_type destruction, copy or assignment
|
|
//! operations other than those exactly corresponding to the insertion of new
|
|
//! elements or deletion of stored elements, which can sometimes compensate in terms
|
|
//! of performance for the extra burden of doing more pointer manipulation and an
|
|
//! additional allocation per element.
|
|
//!
|
|
//! Exception safety: As stable_vector does not internally copy elements around, some
|
|
//! operations provide stronger exception safety guarantees than in std::vector.
|
|
//!
|
|
//! \tparam T The type of object that is stored in the stable_vector
|
|
//! \tparam Allocator The allocator used for all internal memory management
