Test Case taDOM3+/26-taDOM3+-8-NS

taDOM3+ Lock Requests of executed Operation prependChild(contextElementNode, childType, childValue) returns Node

The prependChild operation is executed on the context element node CO and prepends a new child. The context element node CO has still no child nodes before this operation. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the now only child) is returned.

Behavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE
Read Set = CO , Write Set = COFCE COLCE
  • LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]

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

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 NS:

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

Operations must be compatible
