CaptureSpec

@Serializable

data class CaptureSpec(val mode: CaptureMode = CaptureMode.ALL, val include: List<ElementSelector> = emptyList(), val exclude: List<ElementSelector> = emptyList(), val captureWindow: CaptureWindow? = null)(source)

The animation capture configuration (Phase 9): what and when to record, separate from the presentation/layout. Two axes:

WHAT — mode is CaptureMode.ALL (default; every animatable element, today's behavior) or CaptureMode.SELECTED (only include, minus exclude).
WHEN — captureWindow bounds capture to [startTime, endTime]; null = whole run.

Defaults reproduce current behavior exactly (capture-all, no window), so embedding this in TracingConfig is additive. The selectors are not matched against a model here — that author-time validation is Phase 9A.5; the attachment consumes this spec to register emitters selectively (9A.4) and to compose the windowed sink + opening-frame snapshot (9B).

Functions

captures

fun captures(kind: ElementKind, name: String): Boolean

Whether the element identified by kind and name should be captured: in CaptureMode.ALL everything is captured except exclude; in CaptureMode.SELECTED only include is captured, minus exclude. (exclude always wins.) Used by the trace attachment to register emitters selectively (9A.4).

validateAgainst

fun CaptureSpec.validateAgainst(inventory: AnimationInventory): ValidationReport

Validates this capture spec against inventory (9A.5): every include/exclude ElementSelector must name an element the inventory actually exposes for its ElementKind. A selector that names a non-existent element (or names one of the wrong kind) silently captures nothing, so this surfaces the typo at author time with a nearest-name hint drawn from that kind's names.
