Amita Vadhavkar commented on TUSCANY-761:
-----------------------------------------
There is some discussion on Feb4,5,6 2008 IRCs, - here is the summary - what is
the memory cost of having to init number of HelperContexts?
Each one has at constrcution an instance of all HElpers that require to manage
their own state -- i.e. not CopyHelper or
EqualityHelper, but all the others . The state of each of these helpers is not
large until you start registering types
so i think there would only be significant cost if there were duplication in
storage of metadata across typehelpers
so the problem with multiple HelperContexts would be when loading XML
Also, please let know if the issue mentioned in the JIRA still a requirement.
