PrevSib property: Leaf class

Description

This property returns a leaf object associated with the previous sibling leaf. The previous sibling of a leaf is the leaf appearing above the current leaf. If there is no previous sibling and you try to assign it to a variable, you receive a runtime error.

This property is read-only.

Example

The following code traverses the leaves from bottom to top.

While &MYLEAF.HasPrevSib 
   &MYLEAF = &MYLEAF.PrevSib; 
   /* do some processing */ 
End-While;
