Class LaravelUi5\Core\Parameters\Sources\CompositionParameterSource

`implements`	`ParameterSourceInterface`

Self-discovering composition source. Aggregates slot proposals from the active dashboard's artifact tree.

Activation. This source only fires when the active artifact (per Ui5ContextInterface::artifact()) implements Ui5DashboardInterface. For any other artifact (App, Card endpoint, Action, …) the source returns [] — composition is a dashboard-only concept.

Aggregation. The source walks the active dashboard's tree in document order (dashboard → groups → tiles/cards), collecting each SlotProposableInterface artifact's getSlotProposals() map. Conflicting proposals for the same slot resolve first-write-wins; every subsequent conflicting proposal is logged via LoggerInterface::error() with the active dashboard's namespace+version, the slot name, the winning value

source artifact FQCN, and the losing value + source artifact FQCN. The dashboard still renders — the log is informational, not fatal.

Reach. Today this source aggregates the dashboard root only. The aggregator helper is structured to accept any iterable of artifacts so it picks up the full tree without code change once the structural API lands.

Constructor-injects the Container so {@see Ui5ContextInterface} can be resolved lazily. The context is only bound per-request by the ResolveUi5Context middleware; outside a request (e.g. console commands, queued jobs), it's absent. Probing bound() keeps the source happily inert in those contexts.


					
	public

fill(array $slotNames): array

Return a name→value map for the subset of $slotNames this source can fill.

Sources must NOT return keys outside the input set. Returning a key that was not requested raises a LogicException in the pipeline (source integrity check).

Parameters

$slotNames

slot names the pipeline is asking this source to fill

Returns

name → value, only for slots this source filled
