How to get a SDA3.Container object from a Stream object

Question

Gaolai Peng · Nov 8, 2018

I am trying to get SDA3.Container object from a Stream object like following code:

Method HandleECRUpdateRequest(pRequest As CUSTOM.CORE.Message.ECRUpdateRequest, ByRef pResponse As Ens.Response) As %Status
{

               Set tContainer=##Class(HS.SDA3.Container).%New()
               $$$ThrowOnError(tContainer.InitializeXMLParse(pRequest.ContentStream, "SDA3"))

               Set tEventDescription=tContainer.EventDescription

But it tContainer seems to be empty. The tEventDescription is set to empty. I need work on the whole HS.SDA3.Container converted from ContentStream in a ECRUpdateRequest. Doesn't anyone know how to achieve this?

Thanks,

We try to not operate on an entire container, since containers can be arbitrarily large. The API that you are using is one that should be combined with GetNextSDA, to process one streamlet at a time.

set sda3 = ##class(HS.SDA3.Container).%New()
do sda3.InitializeXMLParse(.stream)
while sda3.GetNextSDA(.type, .obj) {
	// process?
}
