Test Case taDOM3/23-taDOM3-8-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 getLastChild(contextElementNode) executed on node CO

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 CO:

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

Operations must be incompatible
