groups of dates

[Jacob Farber]

Hi,
I have a list of objects with dates, and I need to put them into groups per
year. Is there any way to creat something where I can interchange variables
with properties? I need a system like

currentYear = "_"&dateObject.year&""
put archiveList.currentYear

and this would return a list of items inside the list
archiveList.currentYear
I already have archiveList = [#_1999, #_2000, #_2001] etc etc.
How do I go about this???
Im so lost,
Jacob

Hi,

I'm not sure if I understand your question properly, but if you want to
group objects together with a date, you could use a property list like this

MyList = [:]
WhatYear = dateObject.year
If voidP(MyList .getAprop(whatYear) then
-- make a new group for this year
myList.addProp(whatYear, [])
End if
-- now add the dateObject to the 'group list'
GroupList = myList.getAProp(whatYear)
GroupList.add(dateObject)

Doing this will give you a list like
[1999: [obj1, obj2], 2000: [obj3, obj4]...etc ]

Thank you- I will try that. However, I managed to manually creat an array
where numbers were properties, like you list
[1999: [obj1, obj2], 2000: [obj3, obj4]...etc ]
but- If I tried to call something like
put myList.1999
it would give me a messed up array...did this not happen for you?

Yeah - its one of the 'gotchas' using integers as properties in property
lists... You cannot access the value using syntax like
pList.Propname
pList[PropName]

You have to use the syntax

pList.getaProp(propName)
