Class: MarkupLayer

(protected) IPCC.MarkupLayer(viewerControl, markReferencesopt)

(protected) new MarkupLayer(viewerControl, markReferencesopt)

The `MarkupLayer` object is used to group together marks and their associated comments. A layer may be persisted to the web tier using IPCC.ViewerControl#saveMarkupLayer. Also, a layer may be stored in a IPCC.MarkupLayerCollection where it can be retrieved for later use. When creating a layer, mark references may be added. A mark reference is a JSON object that represents a comment that refers to a mark on another layer. When the current user comments on a mark that does not exist in his layer, then his persisted layer record will contain a reference to the mark while the full mark will exist in another record. Because records might be loaded out of order or in an incomplete set, this parameter provides a way to store the mark reference. If the record containing the full mark loads later then the data stored here can be attached to it. After creating a layer, marks may be added and removed from it. The `MarkupLayer` object also provides an event subscription method, to get notified of other types of information. See IPCC.MarkupLayer.EventType.
Parameters:
Name Type Attributes Description
viewerControl string The IPCC.ViewerControl for the loaded document.
markReferences Object | Array.<Object> <optional>
The JSON reference node (or an array of them) from the markup layer record.
Example
// Optionally, specify any references to marks on another layer or layers
var markReference = {
     creationDateTime: "2015-06-12T21:20:58.527Z"

     markUid: "ZZZrOV8yMDE1LTA2LTExVDE5OjU5OjEwLjE3MlpfNDg2dzI5"
     text: "user 1 comment on user 3 mark"
};
