Test Case taDOM3+/26-taDOM3+-2-CO

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 getPrevSibling(contextNode) executed on node CO

The getPrevSibling operation returns the previous sibling node PS of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • readPS
  • usePSNSE

Read and write sets for execution on CO:

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

Operations must be compatible
