|
| AreaAllocator () |
| | Default construct with empty size.
|
| |
|
| AreaAllocator (i32 width, i32 height, bool fastMode=true) |
| | Construct with given width and height.
|
| |
|
| AreaAllocator (i32 width, i32 height, i32 maxWidth, i32 maxHeight, bool fastMode=true) |
| | Construct with given width and height, and set the maximum it allows to grow.
|
| |
|
void | Reset (i32 width, i32 height, i32 maxWidth=0, i32 maxHeight=0, bool fastMode=true) |
| | Reset to given width and height and remove all previous allocations.
|
| |
|
bool | Allocate (i32 width, i32 height, i32 &x, i32 &y) |
| | Try to allocate an area. Return true if successful, with x & y coordinates filled.
|
| |
|
i32 | GetWidth () const |
| | Return the current width.
|
| |
|
i32 | GetHeight () const |
| | Return the current height.
|
| |
|
bool | GetFastMode () const |
| | Return whether uses fast mode. Fast mode uses a simpler allocation scheme which may waste free space, but is OK for eg. fonts.
|
| |
|
|
bool | SplitRect (i32 freeAreaIndex, const IntRect &reserve) |
| | Remove space from a free rectangle. Return true if the original rectangle should be erased from the free list. Not called in fast mode.
|
| |
|
void | Cleanup () |
| | Clean up redundant free space. Not called in fast mode.
|
| |
|
|
Vector< IntRect > | freeAreas_ |
| | Free rectangles.
|
| |
|
IntVector2 | size_ |
| | Current size.
|
| |
|
IntVector2 | maxSize_ |
| | Maximum size it allows to grow. It is zero when it is not allowed to grow.
|
| |
|
bool | doubleWidth_ {true} |
| | The dimension use for next growth. Used internally.
|
| |
|
bool | fastMode_ {true} |
| | Fast mode flag.
