Objective-C


@interface MSFElevationDecoder : NSObject {
  void *swigCPtr;
  BOOL swigCMemOwn;
}

Swift

class MSFElevationDecoder : NSObject

Abstract base class for raster elevation decoders.

  • Checks if this object is equal to the specified object.

    Declaration

    Objective-C

    - (BOOL)isEqual:(id)object;

    Swift

    func isEqual(_ object: Any!) -> Bool

    Parameters

    object

    The reference object.

    Return Value

    True when objects are equal, false otherwise.

  • Returns the hash value of this object.

    Declaration

    Objective-C

    - (NSUInteger)hash;

    Swift

    func hash() -> UInt

    Return Value

    The hash value of this object.

  • Undocumented

    Declaration

    Objective-C

    -(float)getMinimumHeightScale;

    Swift

    func getMinimumHeightScale() -> Float

  • The meta data key naming the DEM pixel encoding, “mapbox” or “terrarium”.

    Declaration

    Objective-C

    + (NSString *)getENCODING_KEY;

    Swift

    class func getENCODING_KEY() -> String!

  • Resolves the decoder for one elevation tile: the tile’s own “dem_encoding” first - two sources of different encodings can sit behind one OrderedTileDataSource, and only the tile knows which answered - then the source’s, then ‘preferred’, then MapBox. Both arguments may be null. The returned decoders are shared singletons.

    Declaration

    Objective-C

    + (MSFElevationDecoder *)
       resolve:(SWIGTYPE_p_std__shared_ptrT_massif__TileData_t *)tileData
    dataSource:
        (SWIGTYPE_p_std__shared_ptrT_massif__TileDataSource_t *)dataSource
     preferred:(MSFElevationDecoder *)preferred;

    Swift

    class func resolve(_ tileData: SWIGTYPE_p_std__shared_ptrT_massif__TileData_t!, dataSource: SWIGTYPE_p_std__shared_ptrT_massif__TileDataSource_t!, preferred: MSFElevationDecoder!) -> MSFElevationDecoder!

    Parameters

    tileData

    The loaded elevation tile, or null.
    dataSource

    The elevation data source, or null.
    preferred

    The decoder the caller was configured with, or null.

    Return Value

    The decoder to decode this tile with. Never null.

    Declaration

    Objective-C

    -(void)dealloc;

    Swift

    func dealloc()
