Test Case taDOM3+/6-taDOM3+-28-LC

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 insertBefore(contextNode, siblingType, siblingValue) executed on node LC

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 LC:

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

Operations must be incompatible
