Struct script::document_collection::DocumentTree
source · struct DocumentTree {
tree: HashMap<PipelineId, DocumentTreeNode>,
}Expand description
A tree representation of Documents managed by the ScriptThread, which is used
to generate an ordered set of Documents for the update the rendering step of the
HTML5 specification.
FIXME: The ScriptThread only has a view of Documents managed by itself,
so if there are interceding iframes managed by other ScriptThreads, then the
order of the Documents may not be correct. Perhaps the Constellation could
ensure that every ScriptThread has the full view of the frame tree.
