I'm not sure of your exact usage, but .locate(int) is part of LocationMapper, and goes with .getLocation(point) essentially, the editor's document is both a DOM document (with ContentNodes, -Elements and -TextNodes), indexable by 'Points' (= defined by parent + child after) but also an OT-aware document indexable by integers (e.g. 'insert the text "hi" at position 4').
Location mapping helps convert between the two one when required - e.g. in this case, the selection range is integer offsets (one for anchor, one for node) and here it's picking the first of the two (Math.min) then converting that integer location to a point. So they are two ways of describing the exact same thing - there are a few things for which points are better (e.g. inserting an element into the tree) and a few for which integers are (e.g. finding the first point, OT operations, ...) so when conversion is required, that's then you use the Location Mapper. hope that helps! - Pat On 1 July 2011 18:17, Anton Starcev <[email protected]> wrote: > Hi, > > Trying to insert doodad in editor, found "locate" method: > > final Point<ContentNode> point = > editor.getDocument().locate(Math.min(range.getAnchor(), > range.getFocus())); > > but can't understand how to use it in source code and in this tutorial: > http://www.waveprotocol.org/code/tutorials/writing-a-doodad > > > Антон Старцев > ______________________________________________________________________ > [email protected] | www.artlebedev.ru >
