Class: Interaction

ol.interaction.Interaction

Abstract base class; normally only used for creating subclasses and not instantiated in apps. User actions that change the state of the map. Some are similar to controls, but are not associated with a DOM element. For example, ol.interaction.KeyboardZoom is functionally the same as ol.control.Zoom, but triggered by a keyboard event not a button element event. Although interactions do not have a DOM element, some of them do render vectors and so are visible on the screen.
