Test Case taDOM3+/6-taDOM3+-24-FC

taDOM3+ Lock Requests of executed Operation getFirstChild(contextElementNode) returns Node

The getFirstChild operation returns the first child FC of the context node CO.

Behavior specified with base operations:

  • readCO
  • useCOFCE
  • readFC
  • useFCPSE
Read Set = CO FC COFCE FCPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:-]
  • LockRequest[node=FC,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node FC

The appendChild operation is executed on the context element node CO and appends 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 appended child node (the now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on FC:

Read Set = FC , Write Set = FCFCE FCLCE
  • LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX] on FC

Operations must be compatible
