Detailed Description

This object allows the user more fine-grained control over the generation of an offline map than the options presented in the standard GenerateOfflineMapParameters.

For example, the parameter overrides allows the user to adjust specific layers so that they:

  • use a different spatial extent or scale range.
  • use custom attribute or geometry settings.
  • are omitted from the download.

An instance of this object can be created from the overall map settings in a pre-existing GenerateOfflineMapParameters by calling OfflineMapTask::createGenerateOfflineMapParameterOverrides. This object gives access to the individual parameter objects via three dictionaries containing generate geodatabase parameters, export tile cache parameters and export vector tile parameters. These can be accessed using generateGeodatabaseParameters, exportTileCacheParameters and exportVectorTilesParameters respectively.

The dictionaries contain the various parameters objects mapped against an OfflineMapParametersKey. An OfflineMapParametersKey represents the service that a particular parameters object is intended for. A key can be constructed using a layer or service feature table. The returned key's OfflineMapParametersKey::type property will indicate which of the three dictionaries contains the desired parameters object and the key can be used to extract it.

Note: A given parameters key/value pair may be shared by multiple layers in the map: for example a single GenerateGeodatabaseParameters could represent the online settings for multiple feature layers which all access the same underlying feature service.

Property Documentation

exportTileCacheParameters : ExportTileCacheParametersDictionary

Returns the dictionary of export tile cache parameters (read-only).

All entries in the dictionary should correspond to ArcGISTiledLayer instances in the online map. If a dictionary entry is removed the corresponding layers will be removed from the offline map without raising an error.


exportVectorTilesParameters : ExportVectorTilesParametersDictionary

Returns the dictionary of export vector tiles parameters (read-only).

All entries in the dictionary should correspond to ArcGISVectorTiledLayer instances in the online map. If a dictionary entry is removed the corresponding layers will be removed from the offline map without raising an error.


generateGeodatabaseParameters : GenerateGeodatabaseParametersDictionary

Returns the dictionary of generate geodatabase parameters (read-only).

All entries in the dictionary should correspond to ArcGISVectorTiledLayer instances in the online map. If a dictionary entry is removed the corresponding layers will be removed from the offline map without raising an error.
