close
protected void close(IElement element, IContext context)
Attempts to close the given element according to options specified in the given context. If the current state of an open element does not permit closing (e.g., a working copy), it remains open. Closing of an element generally involves closing its children and removal of its body from the body cache. This method is called under the element manager lock.Subclasses may override this method, but are not intended to invoke it.
This implementation invokes
((IElementImplExtension)element).
