Member Typedef Documentation

const_iterator

typedef Common::List<Common::Rect>::const_iterator Graphics::DirtyRectList::const_iterator

Const-qualified list iterator.

Member Function Documentation

unionRectangle()

bool Graphics::DirtyRectList::unionRectangle ( Common::Rect &  destRect, const Common::Rect &  src1, const Common::Rect &  src2  )

protected

Returns the union of two dirty area rectangles

merge()

void Graphics::DirtyRectList::merge

(

)

Merges together overlapping dirty areas of the screen

empty()

bool Graphics::DirtyRectList::empty ( ) const

inline

Returns true if there are no pending screen updates (dirty areas)

clear()

void Graphics::DirtyRectList::clear ( )

inline

Clear the current dirty rects list

emplace_back()

template<class... TArgs>

void Graphics::DirtyRectList::emplace_back ( TArgs &&...  args )

inline

Adds a rectangle to the list of modified areas of the screen during the current frame

push_back() [1/2]

void Graphics::DirtyRectList::push_back ( const Common::Rect &  r )

inline

Adds a rectangle to the list of modified areas of the screen during the current frame

push_back() [2/2]

void Graphics::DirtyRectList::push_back ( Common::Rect &&  r )

inline

Adds a rectangle to the list of modified areas of the screen during the current frame

begin()

const_iterator Graphics::DirtyRectList::begin ( ) const

inline

Return a const iterator to the start of the list. This can be used, for example, to iterate from the first element of the list to the last element of the list.

end()

const_iterator Graphics::DirtyRectList::end ( ) const

inline

Return a const iterator to the end of the list.
