List of all members.

Public Member Functions
U32	IsSet (int x, int y) const
	Check if (x,y) is set. Returns non-0 if set, 0 if not.
void	Set (int x, int y)
	Set (x,y) true.
void	Clear (int x, int y)
	Clear the bit at (x,y).
void	ClearRect (const Rectangle2I &rect)
	Clear a rectangle of bits.
void	SetRect (const Rectangle2I &rect)
	Clear a rectangle of bits.
bool	IsRectEmpty (const Rectangle2I &rect) const
	Check if a rectangle is empty.
bool	IsRectSet (const Rectangle2I &rect) const
	Check if a rectangle is completely set.
void	ClearAll ()
	Clear all the bits.
void	SetAll ()
	Set all the bits.
void	CacheY (int y)
	Fast access - cache the y then query the x with IsSetCache.
U32	IsSetCache (int x)
	Query the x at the cached y value.

Detailed Description

template<int WIDTH, int HEIGHT>
class grinliz::BitArray< WIDTH, HEIGHT >

A 2 dimensional bit map.

Maps a bit to a 2 dimensional coordinate. Very useful for efficiently storing 2 dimensional boolean information. Constructed with 'size' parameters templatized.
