Interface IS131Feature
Common contract exposed by every typed S-131 feature (S131HarbourInfrastructure, S131LayoutFeature, S131MetadataFeature, S131OtherFeature). Allows callers to enumerate Features uniformly and dispatch on Family when the high-level classification matters.
public interface IS131Feature
Remarks
S-131 features span all three GML geometric primitives plus the
geometry-less case (container features such as Authority are
modelled as information types in this codebase, but a feature may
still legitimately have no geometry — see FC §B.2). Consumers
should consult GeometryType before
indexing into the coordinate arrays.
Properties
ExtraAttributes
Source attributes that the typed model did not consume.
IReadOnlyDictionary<string, string> ExtraAttributes { get; }
Property Value
Family
The high-level family the feature belongs to.
S131FeatureFamily Family { get; }
Property Value
FeatureType
The raw S-131 feature type code (e.g. "Bollard").
string FeatureType { get; }
Property Value
Geometry
The typed geometry payload (never null; check
IsEmpty for geometry-less features).
S131Geometry Geometry { get; }
Property Value
Id
The GML identifier of the source feature.
string Id { get; }
Property Value
ResolvedReferences
Cross-references from this feature to other objects in the
dataset, resolved via xlink:href. References whose target
did not resolve carry a null
Target and an associated
xlink.unresolved projection diagnostic.
IReadOnlyList<S131ResolvedReference> ResolvedReferences { get; }
Property Value
Source
The originating raw GML feature.
S131Feature Source { get; }
