Over what interface can the user request the abort? Somehow he needs to
communicate with the running process. If you can implement some semaphore or
global class/method/field accesible from Velocity, you could adapt the stop
directive to create your own directive and use it within loops in your
template(s).
If your huge template is of a linear structure, you would need to place the
abort check within the engine - again look at the stop directive on how it can
be done. An engine abort hook might be a better choice, since it does not
require cluttering the templates with the custom directive.
If you find a proper place to place the abort hook in the engine, maybe you can
contribute a patch to make it into future Velocity realeases.

I guess you have to write your own ParserPool and Parser class. Your parser can
override the parse method and abort the parsing or rendering.

Hi everybody,
I'm using velocity within my java project which evaluates quite huge
templates.
The problem is I would like to abort that evaluation if the user wants to.
Is there a proper way to do this using Velocity in Java?
Kind regards
