ShapefileBulkFeatureSource

class ShapefileBulkFeatureSource(val shpUrl: String) : BulkFeatureSource

BulkFeatureSource for ESRI Shapefiles. Downloads the .shp/.dbf/.prj/.cpg quartet from shpUrl (sidecars derived by extension), parses every record through ShapefileLayerFactory, and emits one CachedFeatureRow per record with the geometry extracted as a CachedGeometry and the DBF attributes encoded as a JSON object string.

MultiPatch records produce TriangleMesh renderables on the factory path — those are dropped here because CachedGeometry has no triangle-index model. Use a non-cached source if you need MultiPatch.

Functions

open override fun close()

Release any resources held by the source (HTTP client, etc.). Idempotent default no-op.

fetchAll

open suspend override fun fetchAll(): Flow<CachedFeatureRow>

readBySector

open suspend fun readBySector(sector: Sector): Flow<CachedFeatureRow>

Read only the rows intersecting sector. The default ignores sector and returns fetchAll — a plain network source has no spatial index. A cache-backed source overrides it to serve viewport reads from a spatially-indexed store.
