RE: AW: Returning an object containing various HTML objects

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

Hi:

Can someone provide an example of "dumping"
out the ECS HTML Elements to a PrintWriter or an
OutputStream?

Wouldn't using a StringBuffer be just as efficient?

Thanks:

Alex

It is way more efficient to just dump them out to a PrintWriter or an
OutputStream directly then calling toString on them as that is an
incredibly expensive operation.  I can't actually think of a good reason
to ever call toString on an element in order to output it.
