    Parameters

    text

    A value in OData WKT format.
    sridRequired

    A value parsed from OData WKT (well-known text) format.

  • Spatial Reference System Code, e.g. EPSG SRID. Defaults to 0.

    Declaration

    Swift

    override open var srsCode: Int { get set }

  • Spatial Reference System Name (optional).

    Declaration

    Swift

  • Convert this data value to a string. If the dataType is defined by XML Schema Part 2: Datatypes, then the corresponding lexical format is used. JSON format is used for structured values (arrays and objects).

    Declaration

    Swift

    override open func toString() -> String

    Return Value

    Lexical representation of this data value.
