                       int toIndex)

  Download all object collection from iServer.

  Parameters:

  serviceName - service name.

  datasourceName - datasource name.

  datasetName - dataset name.

  fromIndex - start subscript.

  toIndex - end subscript.

• download

  public void download(java.lang.String fullUrl,
                       int fromIndex,
                       int toIndex)

  Gets the object set in the specified data service address.

  Parameters:

  fullUrl - The data service address. e.g., http://127.0.0.1:8090/iserver/services/data-China400/rest/data/datasources/China400/datasets/City_R

  fromIndex - start subscript.

  toIndex - end subscript.

• downloadAll

  public void downloadAll(java.lang.String fullUrl)

  Gets the all object sets in the specified data service address.

  Parameters:

  fullUrl - The data service address. e.g., http://127.0.0.1:8090/iserver/services/data-China400/rest/data/datasources/China400/datasets/City_R

• downloadDataset

  public void downloadDataset(java.lang.String urlDataset,
                              Datasource datasource)

  Upload a dataset from the server (support point, line and region dataset), and there isn't a dataset with same name in local datasource. It will create a attribute dataset both in local and server, which is used to record the situations that the downloaded dataset has been modified. The synchronization dataset name is "_Table". If failed to download, it will call the requestFaild () method in ResponseCallback; If successsful, it will call requestSuccess() method.

  Parameters:

  urlDataset - The address of the dataset is on the server.

  datasource - Local datasource.

  Notes: urlDataset example: http://192.168.0.131:8090/iserver/services/data-changchun/rest/data/datasources/Changchun/datasets/Edit_Line.

• updateDataset

  public void updateDataset(java.lang.String urlDataset,
                            DatasetVector dataset)

  Update local dataset from the server (support point, line and region dataset), and there isn't a dataset with same name in local datasource. It will create a attribute dataset both in local and server, If failed to update, it will call the requestFaild () method in ResponseCallback; If successsful, it will call requestSuccess() method.

  Parameters:

  urlDataset - The address that dataset is on the server.

  dataset - Local dataset.

  Notes: urlDataset example: http://192.168.0.131:8090/iserver/services/data-changchun/rest/data/datasources/Changchun/datasets/Edit_Line.
