Name

ptr_array: This is a pointer container that uses an underlying boost::array<void*,size> to store the pointers. The class is useful when there is no requirement of dynamic expansion and when no overhead is tolerable.

Synopsis

namespace boost
{      

    template
    < 
        class T, 
        size_t N, 
        CloneAllocator = heap_clone_allocator
    >
    class ptr_array : public implementation-defined
    {
    public: // construct/copy/destroy
        ptr_array();
        ptr_array( std::auto_ptr<ptr_array>& r );

    public: // iterators

    public: // capacity

        template< size_t idx >
        const T&  at() const;
        T&        at( size_t );
        const T&  at( size_t );

        T&        operator[]( size_t );
        const T&  operator[]( size_t ) const;

    public: // modifiers
        void  swap( ptr_array& r );

        template< size_t idx >
        auto_type replace( T* r );
        template< size_t idx, class U >

        template< class U >
        auto_type replace( size_t idx, std::auto_ptr<U> r );

    public: // pointer container requirements
        std::auto_ptr<ptr_array>  clone() const;    
        std::auto_ptr<ptr_array>  release();
        template< size_t idx >
        bool                      is_null() const;
