				boolean	areAllItemsSelectable()
					Are all items in this ExpandableListAdapter selectable?
				long	getCombinedChildId(long groupId, long childId)
					Override this method if you foresee a clash in IDs based on this scheme: Base implementation returns a long: bit 0: Whether this ID points to a child (unset) or group (set), so for this method this bit will be 0.
				long	getCombinedGroupId(long groupId)
					Override this method if you foresee a clash in IDs based on this scheme: Base implementation returns a long: bit 0: Whether this ID points to a child (unset) or group (set), so for this method this bit will be 1.
				long	getNewSelectionForKey(long packedPosition, int keyCode, KeyEvent event)
					Given a keyboard key, let the adapter suggest the group/child to be made the new selected child.
				void	notifyDataSetChanged()

				void	notifyDataSetInvalidated()

				void	onGroupCollapsed(int groupPosition)
					Called when a group is being collapsed.
				void	onGroupExpanded(int groupPosition)
					Called when a group is being expanded.
				void	registerDataSetObserver(DataSetObserver observer)
					Register an observer that is called when changes happen to the data used by this adapter.
				void	unregisterDataSetObserver(DataSetObserver observer)
					Unregister an observer that has previously been registered with this adapter via registerDataSetObserver(DataSetObserver).
