Class AggregationDataProvider

  • java.lang.Object
    • com.supermap.services.providers.AggregationDataProvider
  • All Implemented Interfaces:
    DataProvider, ProviderContextAware


    public class AggregationDataProvider
    extends java.lang.Object
    implements DataProvider, ProviderContextAware
    

    A data service provider with aggregation capabilities.

    A GIS service provider with aggregation capability is a special kind of GIS service provider, which is also known as Service Aggregator in SuperMap iServer. A data service provider with aggregation capability may be referred to as a data service aggregator, which is an aggregator with data service aggregation capability in the aggregator.

    Unlike other service providers (such as WFSDataProvider, WMS service providers), the service aggregator does not directly access remote or local services, or directly inside the GIS functionality package, but by calling different Service type of GIS service provider to achieve GIS functionality. These GIS service providers encapsulate and integrate a variety of different types of services from different sources.

    For example, can implement the aggregation of the data provided by the local SuperMap Objects and the data capabilities provided by the remote WFS service by calling UGCDataProvider and WFSDataProvider (WFS service provider).
