Greetings,
I have a collection of Transaction objects. They have instance variables of category and payee.
A category might be “Office Expense” and a payee might be “Costco” or “Amazon”.
I want to sort by categories and then payees.
Office Expense, Amazon….. ….. …. …. Office Expense, Costco …. … …
Here is some of my code:
sorted := trans asSortedCollection: [:a :b | (a category) < (b category)].
sorted do: [ :tr | | cat pay | cat := tr category. pay := tr payee. stream nextPutAll: (tr myPrintFormat2).
How do I make the sort block sort on both keys?
Sincerely,
Joe.
