Classes
struct	Float2int< power, R >
	Struct for conversion between 0-1 Real and 0-(2^power-1) integer. More...
struct	NonConstType< T >
	Type convertor - NonConstType<T>::Result is a non-const variant of T or T itself if N/A. More...
struct	SingleDeleter
	Template object for automated deletion of pointers (useful in for_each). More...
struct	MultiDeleter
	Template object for automated deletion of field pointers (useful in for_each). More...
struct	UpdateInfo
	Structure providing support for progress update and interruption (used for encoding). More...
Functions
template<typename T >
T	sqr (T i)
	Helper template function computing the square of a number.
template<typename T >
T	cube (T i)
	Helper template function computing the cube of a number.
template<typename T >
T	lShift (T i, T bits)
	Returns i*2^bits.
template<typename T >
T	rShift (T i, T bits)
	Returns i/2^bits.
template<typename T >
T	exp10 (T val)
	This function is missing in earlier GCC versions, here implemented via exp2 and log2.
int	log2ceil (int i)
	Returns ceil(log2(i)).
template<class T >
bool	isNaN (T num)
	A wrapper around isnan() because of compiler support.
int	getCountForDensity (int longLength, int density, int shortLength)
	How many short intervals (shifted by density) can fit into a long interval (discrete).
int	getCountForDensity2D (int width, int height, int density, int sideSize)
	The same as above, but in 2D for squares fitting into a rectangle.
template<class T >
T	checkBoundsFunc (T low, T value, T high)
	General bounds-checking template routine - returns max(low,min(value,high)).
int	countEOLs (const char *s)
	Counts the number of ' ' characters in a C-string.
template<class T >
T *	constCast (const T *toCast)
	Automatic version of const_cast for pointers.
template<class T >
T &	constCast (const T &toCast)
	Automatic version of const_cast for references.
void	checkThrow (bool check)
	Checking a condition - throws std::exception if false.
template<class C >
void	clearContainer (const C &container)
	Deletes all pointers in a container (it has to support begin and end methods).
template<class C >
void	clearQtContainer (C container)
	Clears a QList of pointers (and deletes the pointers).
Variables
const int	powers [31]
	Field containing 2^i on i-th position, defined in modules.cpp.
