Interface ComponentContext

public interface ComponentContext

A component context is opened for each component include that provides a new cell on the cell stack. this is usually the case if the cell name is not empty. The component context is independent from the WCM mode and is always available to the scripts. If the WCM is in edit mode and if the components are editable it also provides an EditContext. Note that an edit context can span several component contexts if not all of the components that are included provide editing. for example pure general purpose scripts.
