Hello,
I have a list which contains of several control points. How can I double check that my desired control point is already in the list or not?
Thanks
In the List's pull method there is a parameter called flags. If you look at the documentation you'll see:
LIST_DO_NOT_REMOVE
Matching entries on the list will be returned by this command, however, the entries will remain on the list. This is useful when creating a directory or routing that doesn't dynamically change.
Using this flag allows you to query the list without pulling anything off of the list. For example:
treenode result = List("FRList1").pull("WHERE value = model().find(\"Processor1\")", 0, 0, 0, 0, LIST_DO_NOT_REMOVE); //If Processor1 is on FRList1 result = Processor1
