ElementContainer isEmpty() method?

[RESTREPO, ALEXANDER G [Non-Pharmacia/1000]]

Hello Everyone:

Does anybody know of a method or technique
to determine if a ElementContainer or any other
ECS Element is empty, i.e., it contains no Elements?

Many Thanks:

Alex Restrepo

I'd also like to know if it exists... I used:

myTR.removeElement(td1.hashCode() + "")
    .removeElement(td2.hashCode() + "")
    .removeElement(td3.hashCode() + "");
