How about this
it's with parent/children structur
ClassMethod addToQ(inID,inData1,inData2,inData3....) as %Status
{
set o=..%New()
//link to the parent queue
set o.rParentSetObjectId(inID)
set o.p1=inData1
set o.p2=inData2
set o.p3=inData3
...
quit o.%Save()
====
also be aware that there is no guarantee with the object exposure for
the order of retreival
ie
for 1:1:..rItems.Count() {
process ..rItems.GetAt(i)
}
Does not guarantee the order !!!!!!!!!!!!!!
u need some SQL
to get the first item
&sql(select %ID into :xID from class.QueueItems
where rParent=:inQueueID
order by childsub
)
is the only guaranteed method !!!
