detect_data_modality() [2/2]

DataModality MayaFlux::Kakshya::detect_data_modality	(	const std::vector< DataDimension > &	dimensions,
		const DataVariant &	source
	)

Detect data modality from dimensions and source variant scalar type.

Resolves ambiguous cases where dimension roles alone are insufficient, primarily the TIME-only case where decimal, integer, and complex types would otherwise all collapse to the same result.

Parameters

dimensions	Vector of data dimensions with role information.
source	Original DataVariant used to produce the dimensions.

Returns

Detected DataModality type.
