org.exoplatform.caldav.ics.IcsReader

@Component
public class IcsReader
extends Object

Reads a remote calendar object into the occurrences it produces over a window.

Two shapes arrive here and both must be handled, because which one a deployment sees is the server's choice, not ours. A server honouring CALDAV:expand answers one VEVENT per occurrence, times rewritten to UTC and the rule gone — the shape the browser connector has always parsed, since Stalwart expands. A server that ignores expand answers the stored object, rule and all, and the occurrences have to be produced here.

The second branch is the one that matters for the migration: whether a given server expands is unproven for BlueMind, and an engine that only worked against expanding servers would fail silently — not by erroring, but by showing a single event where a weekly series should be.
