doneEditMemo()

doneEditMemo(): void

This clears and edit memo storage to allow for further history functions to be called. Calls the complete function if present, and pushes the memo to the history memo stack.

This should be called when a tool has finished making a change which should be separated from future/other changes in terms of the history. Usually that means on endCallback (mouse up), but some tools also make changes on the initial creation of an object or have alternate flows and the doneEditMemo has to be called on mouse down or other initiation events to ensure that new changes are correctly recorded.

If the tool has no end callback, then the doneEditMemo is called from the pre mouse down callback. See ZoomTool for an example of this usage.

createAnnotationMemo()

static createAnnotationMemo(element, annotation, options?): object

Creates an annotation memo storing the current data state on the given annotation object. This will store/recover handles data, text box and contour data, and if the options are set for deletion, will apply that correctly.
