ITBaseObject

PURPOSE: Represents one ArcGIS Feature Service connection and manages the layers discovered for that service.

BEHAVIOR: Stores the service URL, service name, and a layer list. The open methods connect to the service and populate available layer metadata, whileOpenLayer opens a single layer by id.

USAGE: Use this class to open a Feature Service endpoint and inspect or access its layers.

server = TGIS_ArcGISFeatureServer()       server.Open(url)       layer = server.OpenLayer(url, "0")

CONSTRAINTS: This class derives fromTGIS_ObjectDisposable. The layer list belongs to the server object and follows its lifecycle.

  fs := TGIS_ArcGISFeatureServer.Create;
  try
    fs.Open('https://sampleserver6.arcgisonline.com/arcgis/rest/services/Wildfire/FeatureServer');
    GIS.Lock;
    try
      for fl in fs.Layers do begin
        ll := GisCreateLayer(fl.Name, fl.Path);
        GIS.Add(ll);
        ll.ParamsList.Assign( fl.DrawingInfo ) ;
      end;
    finally
      GIS.Unlock;
