    • createStructType

      public static nz.org.riskscape.engine.types.Struct createStructType(nz.org.riskscape.engine.types.CoverageType coverageType)

      The most minimal struct that a GridCoverageRelation will produce. This is here solely as a best-efforts link between this class and ToRelation so we can realize a dynamic expression with to_relation.
