Test Case taDOM3+/6-taDOM3+-25-CO

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 prependChild(contextElementNode, childType, childValue) executed on node CO

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.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyFCPSE

Read and write sets for execution on CO:

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

Operations must be incompatible
