Include dependency graph for FontResourceGraph.h:

This graph shows which files directly or indirectly include this file:

Classes
class	donner::svg::components::ScopedFontResourceRender
	A render scope accepts exclusions only after its caller completes the corresponding traversal. More...
class	donner::svg::components::FontResourceGraph
	A frame-local snapshot of the font dependencies and resolved reference ranges of the render tree. More...
struct	donner::svg::components::FontResourceGraph::Collection
	Owned result of following the prepared references reachable from a target. More...
class	donner::svg::components::FontResourceGraphCache
	Bounded reuse within one render preparation or font-refresh traversal. No entry survives the operation, and preparation changes invalidate both the graph and its target collections. More...
struct	donner::svg::components::FontResourceGraphCache::Stats
	Work and reuse counters for one cache lifetime. More...
struct	donner::svg::components::FontResourceGraphCache::Entry::TargetCollection
	Cached target result bound to the render scope that last reused it. More...

Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.
namespace	donner::svg
	Donner SVG library, which can load, manipulate and render SVG files.
namespace	donner::svg::components
	Contains the implementation of the Donner ECS,.

Functions
void	donner::svg::components::InvalidateFontResourcePreparation (Registry &registry)
	Advance the document's font-preparation epoch so cached dependency evidence is rebuilt.
