data class A11yNode(val nodeId: String, val composableName: String, val bounds: Rect, val contentDescription: String?, val isTouchTarget: Boolean, val textColor: Color?, val backgroundColors: List<Color>, val isFocusable: Boolean, val isMergedDescendant: Boolean, val depth: Int, val role: A11yRole? = null, val effectiveTouchBounds: Rect? = null)

Normalized representation of one UI semantics node scanned by the accessibility rules.

Constructors

constructor(nodeId: String, composableName: String, bounds: Rect, contentDescription: String?, isTouchTarget: Boolean, textColor: Color?, backgroundColors: List<Color>, isFocusable: Boolean, isMergedDescendant: Boolean, depth: Int, role: A11yRole? = null, effectiveTouchBounds: Rect? = null)

Properties

backgroundColors

val backgroundColors: List<Color>

Candidate background colors sampled behind the node.

val bounds: Rect

Pixel bounds relative to the scanned root.

val composableName: String

Best-effort composable or role name used in reports.

contentDescription

val contentDescription: String?

Accessible label exposed by the node, if any.

Depth in the semantics tree.

effectiveTouchBounds

val effectiveTouchBounds: Rect?

Effective pointer target bounds in root pixels for clickable nodes.

val isFocusable: Boolean

True when the node can participate in focus traversal.

isMergedDescendant

val isMergedDescendant: Boolean

True when the node is inside a parent that merges semantics.

val isTouchTarget: Boolean

True when the node exposes a click action.

val nodeId: String

Stable id for grouping issues that belong to the same semantics node.

val role: A11yRole?

Accessibility role mapped from the platform semantics role, if any.

val textColor: Color?

Foreground text color when it can be extracted.
