Public Member Functions
void	reset ()
	Reset counters before a full render-tree rebuild.
bool	reserve (std::size_t generatedEntities, std::size_t referenceDepth, std::size_t traversalDepth)
	Atomically reserve one fully preflighted branch before creating any entities.
void	reject ()
	Latch rejection when preflight itself crosses a hard limit.
std::size_t	instances () const
	Shadow branches admitted in the current render-tree rebuild.
std::size_t	generatedEntities () const
	Generated shadow entities admitted in the current rebuild.
bool	rejected () const
	Whether branch preflight exceeded a resource limit.

Static Public Attributes

	Maximum shadow branches instantiated during one render-tree rebuild.
static constexpr std::size_t	kMaximumGeneratedEntities = 16 * 1024
	Maximum generated shadow entities retained during one render-tree rebuild.
static constexpr std::size_t	kMaximumReferenceDepth = 64
	Maximum acyclic href-reference nesting within one branch.
static constexpr std::size_t	kMaximumTraversalDepth = 256
