slingSuperResourcetype doubt in the below article

Hi All,

One of the article mentions this, but I am not getting what exactly it means. Any thoughts on this will be helpful.

slingSuperResourcetype: It is used to inherit / extend components from foundation or other components. There is a good example to understand it completely. Consider components a , b, c, x, y with the below mentioned properties for each of them :

• /
  • a
  • b
    • sling:resourceSuperType = a
  • c
    • sling:resourceSuperType = b
  • x
    • sling:resourceType = c
  • y
    • sling:resourceType = c
    • sling:resourceSuperType = a

The type hierarchy of

• /x is [ c, b, a, <default>] while for
• /y the hierarchy is [ c, a, <default>]

because /y has the sling:resourceSuperType property whereas /x does not and therefore its supertype is taken from its resource type.
