IServiceHttpInfo

Overview

The IServiceHttpInfo interface allows to get information about a Schema that is related with a data abstract service.

This interface is implemented by the DataAbstractService class to get information about the related service schema:

method DataAbstractService.GetContentStream(aPath: System.String; out aCloseStream: System.Boolean; out aContentType: System.String): System.IO.Stream;
begin
  if not AllowSchemaAccess or not AllowHttpSchemaAccess then
    raise new DAException('Schema access has been disabled (HTTP)');

  result := new MemoryStream();
  ServiceSchema.Serialization.SaveToStream(result);
  result.Seek(0, SeekOrigin.Begin);
  
  aCloseStream := true;
  aContentType := 'text/xml';
end;

and is used in the all HTTP Server Channels, such as HttpSysServerChannel, IpHttpServerChannel, etc. to build the following response:

protected void HandleHttpRequest(object aSender, OnHttpRequestArgs ea)
{
...
  IServiceHttpInfo lHttpInfo = lService as IServiceHttpInfo;
  if (lHttpInfo != null)
  {
    bool lCloseStream;
    string lContentType;
    ea.Response.ContentStream = lHttpInfo.GetContentStream(lSubPath, out lCloseStream, out lContentType);
    ea.Response.CloseStream = lCloseStream;
    ea.Response.Header.ContentType = lContentType;
    return;
  }
...
}

The IServiceHttpInfo interface is used internally. You do not need to use this class directly.
