Test Case taDOM3/23-taDOM3-28-CO

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

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Behavior specified with base operations:

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

taDOM3 Lock Requests of checked Operation insertBefore(contextNode, siblingType, siblingValue) executed on node CO

The insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There does not exist a previous sibling, so the context element node was the first child of the parent node PA and the inserted new sibling node (the new first child of PA) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOPSE
  • modifyPAFCE

Read and write sets for execution on CO:

Read Set = CO , Write Set = PAFCE COPSE
  • LockRequest[node=CO,lock:NR,PSE:EX,NSE:-,FCE:-,LCE:-] on CO
  • LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:-] on CO

Operations must be compatible
