using this approach the filter functions still need to reference the
view to get optional filter parameters correct. For example, if you
want to filter based on a user inputed text field you can just do this:
collection.filterFunction = filter.filterFunction (textFld.text);
since the filter functions can not accept parameters.
In thinking about this I am wondering if this would work instead:
FilterClass.filterByName(collection,textFld.text);
Then within the class, the static method "filterByName" will handle
assigning a filter function to the collection and using the
"textFld.text" to filter.
Is there something that I am missing with this approach.

I'm using a FilterClass, which holds just the filterFunction and

Every collection, which needs filtering, gets an instance of this
FilterClass by assigning collection.filterFunction =
filter.filterFunction;

I would like to attempt to separate my filter functions from my view
so that I am not duplicating code when two views share similar filter
functions. My idea was to create a class that contains a
ListCollection and all the appropriate FilterFunctions for that
collection. The FilterFunctions would then be applied by methods in
that class.
The problem I am having is that I can't pass any parameters to the
FilterFunction when I assign it to the specific ListCollection. The
FilterFunction seems like it needs to be tightly coupled with the
view in order to work.
To work around this, for application wide filters, I am saving a
filter value on my model and then referencing the model from my
FilterFunction (which still isn't ideal). However in some cases this
isn't appropriate since the filter value doesn't really need to be
persisted over the entire application.
Does anyone have any thoughts on how to accomplish this?
Thanks for the help,
Kevin
