the edit context
an editing handle that is used to initialize the state of the object being created.
This method is called by EditController to retrieve the handles for editing.
For example, point list translation/insertion/deletion handles, handles to modify a circles center and radius,... By default, all editors include a shape translation handle.
This is also used for creation, when the "create-by-template" approach is used to create new shapes.
The context to retrieve the handles for.
An Editor describes how features or shapes should be edited and created.
It creates handles that are used by the EditController to edit features and the CreateController to create new features.
Edit handles generally correspond to the shape of the feature being edited. For example, to edit a four-sided polygon, an Editor might create five handles: four to move each of the individual vertices of the polygon (see getEditHandles), and a fifth one to move the polygon as a whole (see createTranslateHandle).
