The context of Timelines

This page applies to Harlequin v13.1r0 and later; and to Harlequin MultiRIP but not Harlequin Core

Another feature of timelines is that you can register or pin things onto a timeline.

When a timeline is created, as well as specifying the extent, the units and the title of the timeline, a context pointer is also provided. This context has a wide range of uses. In the case of the RIP core, when creating the core job timeline, it attaches a reference to the internal core job structure. What this means is that for every handler that gets called with an event on that timeline it immediately has access to the contextual information for that timeline. It is possible to attach any number of separate pieces of information to a timeline, and third parties can attach their own information to timelines.
