Is there a way to make a copy of what's in my cache (getServletContext())
and make changes to that local copy, independent of whether the cached
object implements Cloneable()?
In order to speed up my XSLT I thought I would preload them (their
Transformer objects) into app scope and simply retrieve it as needed for
transforms.
This works fine except I just remembered that I need to set attributes on
these XsLT Transformer objects. Now, I am PRESUMING that this means that I
would then be locking up the servlet context each time I set one of these
parameters so then it seems I should clone() the object locally. That way I
could set the params locally without affecting (or locking) the cached
version). BUT Transfomer does not appear to implement the Cloneable()
interface.
Is there a way around this? Am I by any chance wrong about what's actually
happening here? Can anyone make a suggestion?
Here's what I'm doing basically:
ServletContext application = getServletContext();
application.setAttribute("TEMPLATES_HASH",templates);
(where templates is a Hashtable containing Transformer objects)
Thanks.
