Here is the way I organize my work around Witango to implement what I
consider to be object oriented. I began doing this prior to the
implementation of Presentation Actions Witch Help even more to make
separation of business logic, presentation and data more of an attainable
model.
So here goes:
I use 1 taf as if it were a class object so for instance lets take something
like users and providing 1 sharable/reusable set of code to call to interact
with this class called users. I then in witango studiobuild the outer
application tree for the class, which would be comparable to methods, with
some kind of ifelse decision tree.
IF <@arg _method> = memberServices
if <@arg _mod>=manageAccount
<@arg _function>=listAccountProfile
<@arg _function>=updateAccountProfile
elseif<@arg _mod>=manageOrders
<@arg _function>=searchOrders
<@arg _function>=viewCurrentOrders
<@arg _function>=viewUnbalancedOrders
else ERROR
ELSEIF <@arg _method> = userAdmin
Then another tree as above however custom to the functionality of user admin
add a user, update the profile etc....
ELSEIF <@arg _method> = userAdmin
the standard I use is _method for the outer most IF
_mod (for module) for each module of the class, most often you find these
break down along the lines of oop concept of public, private and protected
methods
_function for the underlying function that is to be preformed.
so at the very least a URL string must contain all of these args or else the
app will error.
The next step is what to you do inside the function. In the past I either
placed custom business logic or a builder in place at that level, the trick
here is not to cross the line and begin using results or accumulated results
to display the html output to your users but rather as I did in the past use
the results to interpret some piece of data returned in an if/else decision
tree that determined which presentation file to include.
Since I'm recently new to the 4.5 Witango editor and have been slogging
along for years with my old tried and true version 3.52 the implementation
of presentation actions is a great addition. I've been experimenting with
these and they work great and if you can keep your cursor out of the results
editor you stand a chance of not placing presentation in the taf object.
I would even like to experiment more with the tango class files because from
what I see there, I have a great deal of taf that is doing the work of tcf.
and could be moved there.
just my spin on things, but by no means a completely accurate oop use of
Witango. I've done some work with OO Design using Rational Rose and Visio
UML model and have implemented some of these models in java(Jakarata and
Cocoon 2.0) and most recently in .Net and what I've found is no matter which
mouse trap you are using you must first understand the nature of the mouse
you are trying to trap and define it.
