Test Case taDOM3/25-taDOM3-28-LC

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 to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.

Behavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyFCPSE
Read Set = CO , Write Set = COFCE FCPSE
  • LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:-]
  • LockRequest[node=FC,lock:-,PSE:EX,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
