Types

data class LayoutPassEntry(val viewName: String, val measureCount: Int, val layoutCount: Int, val totalMeasureNs: Long, val totalLayoutNs: Long)

Aggregated measure and layout timings for one Android View class name.

LayoutPassSnapshot

data class LayoutPassSnapshot(val totalMeasureCount: Int = 0, val totalLayoutCount: Int = 0, val totalMeasureNs: Long = 0, val totalLayoutNs: Long = 0, val entries: List<LayoutPassEntry> = emptyList())

Immutable process-local snapshot of sampled View layout work.

LayoutPassTracker

object LayoutPassTracker

Opt-in process-local sampler for Android View measure and layout calls.

MountedNode

class MountedNode(var vnode: VNode, val view: View, var children: List<MountedNode> = emptyList())

Mutable renderer-owned association between a committed VNode and its Android View.

NodeTypeBindingStats

data class NodeTypeBindingStats(val rebound: Int = 0, val patched: Int = 0, val skipped: Int = 0)

Binding outcome counters for one declarative node type.

RenderPatchOperation

enum RenderPatchOperation : Enum<RenderPatchOperation>

Operations emitted by the renderer's reconciliation and binding pipeline.

RenderPatchRecord

data class RenderPatchRecord(val operation: RenderPatchOperation, val type: NodeType, val key: Any?, val parentKey: Any?, val index: Int, val moved: Boolean = false, val detail: String? = null, val toolingMetadata: UiNodeToolingMetadata? = null)

One ordered renderer operation for diagnostics and preview tooling.

data class RenderTreeCommitEffect(val operation: AndroidViewOperation, val nodeKey: Any?, val commit: () -> Unit)

Deferred Android View lifecycle callback executed after structural commit.

RenderTreeCommitFailure

data class RenderTreeCommitFailure(val operation: AndroidViewOperation?, val nodeKey: Any?, val cause: Throwable)

Isolated lifecycle failure captured during commit or disposal.

RenderTreeNode
