Test Case taDOM3/30-taDOM3-8-PA

taDOM3 Lock Requests of executed Operation insertAfter(contextNode, siblingType, siblingValue) returns Node

The insertAfter operation is executed on the context element node CO and inserts a new next sibling node after the context node CO. There does not exist a next sibling, so the context element node was the last child of the parent node PA and the inserted new sibling node (the new last child of PA) is returned.

Behavior specified with base operations:

  • readCO
  • modifyCONSE
  • modifyPALCE
Read Set = CO , Write Set = PALCE CONSE
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:EX,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:-,LCE:EX]

taDOM3 Lock Requests of checked Operation getLastChild(contextElementNode) executed on node PA

The getLastChild operation returns the last child LC of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCOLCE
  • readLC
  • useLCNSE

Read and write sets for execution on PA:

Read Set = PA NS PALCE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:ER] on PA
  • LockRequest[node=LC,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on PA

Operations must be incompatible
