Validates detector inputs and configures destination for one coordinate kind. Resolve kind from the validated DetectorConfiguration, never from NLayers or DetId. Returns true on success; on failure, returns false and leaves destination unchanged. Call once per present kind during detector initialization, outside iteration and candidate loops.

bool o2::itsmft::tracking::indexTableConfigurationsMatch ( const o2::itsmft::IndexTableUtilsCore &  a, const o2::itsmft::IndexTableUtilsCore &  b, int  activeSurfaceCount  )

inlinenoexcept

True iff all fields stored by setIndexTableParams match between a and b. Used to verify that a non-FirstPass iteration matches the TimeFrame-owned configuration before reusing or resorting its LUT.

Definition at line 45 of file IndexTableConfiguration.h.

loadTimeFrameSources()

		std::vector< std::vector< uint32_t > > *	clusterSizesBySurface = nullptr
	)

Reset, decode, and normalize all sources into a configured TimeFrame. ROF records supply cluster ranges only. The workflow binds runtime ROF views after loading and owns timing validation independently. Invalid input throws. On failure, the caller must reset the frame before reuse; partially loaded data must not be published.
