Does deleting a StreamContainer delete the contained Stream Object?

#ObjectScript #Caché #Ensemble #InterSystems IRIS for Health

Hey everyone.

I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.

Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.

From looking in the class, the  %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.

Am I looking in the right place, or is there a extended class for Ens.StreamContainer that does in fact delete the %Stream.Object
contained within the Ens.StreamContainer?

Hi @Julian Matthews

The Ens.StreamContainer class is a %Persistent class and it stores the different types of stream in it. So, If you delete the row/record by id / or by query it will delete the entry as well as the stream contents(it's also part of the row) from the Ens.StreamContainer table. So, be cautious before deleting the container. %OnDelete  callback method is used to do some additional function while deleting the object.
