Struct LightIntensityDistribution 

pub struct LightIntensityDistribution<'m, 's> { /* private fields */ }

Borrowed projection of IfcLightIntensityDistribution: a luminaire’s photometric distribution, as a curve type plus its sampled data rows.

Implementations

impl<'m, 's> LightIntensityDistribution<'m, 's>

pub fn light_distribution_curve(&self) -> StyleResult<&'m str>

The LightDistributionCurve attribute: a token from IfcLightDistributionCurveEnum (TYPE_A, TYPE_B, TYPE_C, NOTDEFINED).

This token is not decoration – it names which photometric convention the angles in Self::distribution_data follow, so the same numbers mean different directions under Type A, B, and C. A consumer that ignores it will aim the distribution wrongly. Returned as the raw schema token for the same reason as LightEmissionSource.

pub fn distribution_data(&self) -> StyleResult<Vec<EntityId>>

The DistributionData attribute: at least one IfcLightDistributionData reference.

The schema declares LIST [1:?], so an empty list is a typed error rather than an empty iterator that silently renders an unlit luminaire.
