Public Types
typedef shore::uint64_t	int_type
	The proxied type.

Public Member Functions
	intpack (const size_t initialsize=0)
	Constructor; initial values are zero-initialized.
	intpack (const intpack &other)
	Copy constructor, calls operator=.
intpack &	operator= (const intpack &other)
	Assignment: clear(), repack(), resize(), then copy the data.
	~intpack ()
	Destructor; release memory.
void	resize (const size_t new_size)
	Resize; new values are uninitialized.
void	repack (size_t new_nbit=std::numeric_limits< size_t >::max())
	Reencode; sets capacity equal to size.
void	repack_for (int_type v)
	Reencode such that we are able to store v.
void	reserve (const size_t new_capacity)
	Increase the capacity to accomodate at least the requested number of elements.
void	clear ()
	Set size to zero.
void	push_back (const int_type n)
	Add an element.
void	pop_back ()
	Remove element.
template<typename Iter >
void	append (Iter beg, Iter end)
	Append elements in range; all elements must be <= max_value.
reference	operator[] (const size_t idx)
	Access element at position idx.
const_reference	operator[] (const size_t idx) const
	Access element at position idx.
reference	front ()
	Access first element.
const_reference	front () const
	Access first element.
reference	back ()
	Access last element.
const_reference	back () const
	Access last element.
size_t	nbit () const
	Get number of bits per element.
size_t	size () const
	Get number of elements.
bool	empty () const
	Test if size==0.
int_type	max_value () const
	Get the maximum value that can be stored.
const char *	data_begin () const
	Pointer to the start of the underlying storage.
const char *	data_end () const
	Pointer to the end of the underlying storage.
void	end_polish ()
	Set the dummy bytes included by data_end() to zero.
iterator	begin ()
	Get the (proxy) iterator to the first element.
iterator	end ()
	Get the (proxy) iterator to the end of the intpack.
const_iterator	begin () const
	Get the (proxy) iterator to the first element.
const_iterator	end () const
	Get the (proxy) iterator to the end of the intpack.

Static Public Attributes
static const size_t	GROWTH_ATTENUATOR =1
	Lets the container grow by factor 1.5 on resize.

Detailed Description

Vector for dynamic bit-width integer storage.
