TdxAzureMapResponse Class

The base class for data transfer objects designed to store responses from Azure Maps servers.

#Declaration

Delphi
TdxAzureMapResponse = class(
    TdxRestServiceResponse
)

#Remarks

TdxAzureMapResponse is the base class for all DTOs (data transfer objects) that return information in response to queries sent by auxiliary Azure Maps information providers.

#Main API Members

The list below outlines key members of the TdxAzureMapResponse class. These members allow you to obtain general server response information.

ErrorInfo

Provides access to detailed error information if the current server query is not successful.

This property is initialized only if a server returns error information.

IsSuccess

Identifies if the current server query is successful.

If the IsSuccess property returns False, you can use ErrorInfo and StatusCode properties to obtain detailed information on the error.

QueryParams
Provides access to information returned in response to the current query.
StatusCode
Returns the server response status code.

#Code Example: Validate Server Response

The code example in this topic section demonstrates a function that checks if an Azure Maps server response is valid. The function returns False and displays a message box with the corresponding error message if a server query fails.

uses
  dxMessageDialog;  // This unit declares the dxMessageDlg global function
// ...

function TMyForm.ValidateServerResponse(AResponse: TdxAzureMapResponse): Boolean;
begin
  if AResponse <> nil then
  begin
    Result := AResponse.IsSuccess;
    if not Result and Assigned(AResponse.ErrorInfo) then
      dxMessageDlg(AResponse.ErrorInfo.Message, TMsgDlgType.mtError, [mbOK], 0);
  end
  else
    Result := False;
end;
