AsyncSVGDocument.h File Reference

AsyncSVGDocument is the editor-owned wrapper around svg::SVGDocument. It gates canvas, tool, and application mutations through the CommandQueue, applies incremental source-pane edits through a separate guarded seam, and provides the snapshot hand-off to the render thread. More...

Detailed Description

AsyncSVGDocument is the editor-owned wrapper around svg::SVGDocument. It gates canvas, tool, and application mutations through the CommandQueue, applies incremental source-pane edits through a separate guarded seam, and provides the snapshot hand-off to the render thread.

The editor now renders on a dedicated AsyncRenderer worker. The worker shares the live document registry under ConcurrentDom access guards, while frame-version and document-generation counters let the UI discard stale results and preserve valid compositor state across structural reparses.

Class Members
bool	appliedCommands = false
vector< Entity >	cacheInvalidatedElements	Entities whose existing rendered pixels may have changed because of an incremental command.
bool	hadPriorAppliedCommandsOnRollback = false	A prior command in this flush still changed source before that rollback.
bool	onlyTransformCommands = false	True only when every applied command changed an element transform. An overlay guide captured before a drag may be safely projected through these version advances without rereading clip resources; any other edit invalidates that immutable guide cache.
bool	preserveUndoOnReparse = false
bool	removedElements = false	True when at least one flushed command removed an element from the live document.
bool	replacedDocument = false
bool	rolledBackReplacementBatch = false	A failed replacement batch restored its exact pre-command source.
