Hi - Iâm after some ideas or maybe previous examples that might guide me in the best approach of wrapping a low level library (essentially the Jira connector that Phil demoâd at Pharo days this year). There are some low level commands that will fetch json arrays for you given a âliraâ instance- e.g: board := JiraBoard fromJira: jira named: âProject'. sprints := board sprintsFrom: jira. My question is related to building on top of this - and its a style question. I want model objects that wrap the json arrays and let me navigate things a bit more simply, and query details more naturally - however I canât decide whether my model objects should âcontainâ a jira when you instantiate them - which can be re-used for subsequent queries - OR - whether I should view jira as a from of context, and keep passing it to methods when I need to retrieve more details, or child objects? e.g. myBoard := ModelBoard fromJira: jira named: âProjectâ. mySprints := myBoard sprints. âNo need to pass the jira againâ. vs. mySprints :- myBoard sprintsIn: jira. Iâm wondering if anything might guide me one way or the other? Is one more tasteful/elegant than the other? Tim
