donner::editor::CommandQueue Class Reference

Classes
struct	FlushResult

Public Member Functions
void	push (EditorCommand command)
	Push a command onto the queue. UI thread only.
FlushResult	flush ()
	Drain and coalesce the pending commands. Returns the effective set of commands to apply, in the order the application should issue them. After flush() returns, the queue is empty.
bool	empty () const
	Whether the queue currently holds any pending commands. Useful for frame-skip optimizations (no need to re-render if nothing changed).
std::size_t	size () const
	Number of un-coalesced commands currently pending. Coalescing happens at flush() time, so this is the raw count, not the effective count.
void	clear ()
	Drop everything pending without applying. Useful for tests and for the "abort drag" cancel path.
