Method ParentLevel

tree/nodebase.go:161–173

ParentLevel finds a given potential parent node recursively up the hierarchy, returning the level above the current node that the parent was found, and -1 if not found.

(parent Node)

// hierarchy, returning the level above the current node that the parent was
// found, and -1 if not found.
func (n *NodeBase) ParentLevel(parent Node) int {
	parLev := -1
	level := 0
	n.WalkUpParent(func(k Node) bool {
		if k == parent {
			parLev = level
			return Break
		}
		level++
		return Continue
	})
	return parLev
}

// ParentByName finds first parent recursively up hierarchy that matches
// the given name. It returns nil if not found.
