Test Case taDOM2/23-taDOM2-5-CO

taDOM2 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:CX,PSE:-,NSE:-,FCE:-,LCE:EX]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]

taDOM2 Lock Requests of checked Operation getNextSibling(contextNode) executed on node CO

The getNextSibling operation returns null because the context node CO is the last child of parent node PA and no next sibling node NS exists.

Bahavior specified with base operations:

  • readCO
  • useCONSE
  • usePALCE

Read and write sets for execution on CO:

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

Operations must be compatible
