A11yNodeExtractor

class A11yNodeExtractor

Walks a Compose semantics tree and converts each SemanticsNode to an A11yNode.

Use the unmerged tree to see all rendered nodes including merged descendants:

Test: composeTestRule.onRoot(useUnmergedTree = true).fetchSemanticsNode()
Production: SemanticsOwner.rootSemanticsNode via extract(SemanticsOwner)

Functions

fun extract(rootNode: SemanticsNode): List<A11yNode>

Recursively extracts all nodes from the tree rooted at rootNode. Returns a flat list in depth-first order.

fun extract(owner: SemanticsOwner): List<A11yNode>

Entry point for production use. Requires opting in to the internal Compose UI API needed to access SemanticsOwner.
