  • java.lang.Object
    • com.supermap.data.EngineType

  • public class EngineType
extends java.lang.Object
    Defines the spatial database engine type constants.

    The spatial database engine is more than a regular database management system, and besides the necessary functionality of a regular database management system, it provides specific storage and management function for spatial data.

    SuperMap SDX+ is the spatial database engine of SuperMap. All kinds of spatial geometric objects and images can be stored in relational database via SDX+ engine to become a spatial database which can implement incorporate storage of spatial data and attribute data.

    For different types of datasources, different types of engines are needed, for file datasource, or UDB datasource, SDX+ for UDB is needed, the engine type isUDB. The current engine types supported areUDB and image read onlyIMAGEPLUGINS.

      • IMAGEPLUGINS

        @Deprecated
public static final EngineType IMAGEPLUGINS
        Deprecated. Obsolete, Cache replacement of SCI isRest. Read-only engine for image file, such as common image formats like BMP, JPG, TIFF, the SuperMap-defined SIT format, 2D map cache configuration file format SCI, etc.

        While loading 2D map caches, the engine type should be employed. Besides, it is needed to set the DatasourceConnectionInfo method of the setServer() class to the 2D map cache configuration file (SCI).

      • OGC

        public static final EngineType OGC
        The OGC engine type for Web datasource.

        The current version supports following types, they are WMS, WFS, WCS and WMTS.

      • UDB

        public static final EngineType UDB
        The UDB engine type.

      • SuperMapCloud

        public static final EngineType SuperMapCloud
        SuperMap Cloud Services. It's a read only engine and can not be created.

      • GoogleMaps

        public static final EngineType GoogleMaps
        GoogleMaps engine. It's a read only engine and can not be created.

      • BaiDu

        public static final EngineType BaiDu
        Baidu map engine, it is a read only engine and can be created.

      • Rest

        public static final EngineType Rest
         REST map services engine. It's a read only engine and can not be created.
 The server address is map server address on iServer, when open Rest map service datasource, e.g. World map: http://192.168.120.1:8090/iserver/services/map-world/rest/maps/World
 
 
        From 811,  REST engine supports to open sci cache directly, include REST web cache and cache files generated by iDesktop. This method replacedIMAGEPLUGINS. The parameter set as absolute path of sci cache files while opening directly.
        
 
        Note: left of "index range" should be set as -180, and top should be set as 90, when generate map cache with latitude and longitude coordinates, otherwise, it could not be displayed on mobile.
