Test Case taDOM3+/25-taDOM3+-6-CO
taDOM3+ Lock Requests of executed Operation prependChild(contextElementNode, childType, childValue) returns NodeThe 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 getFirstChild(contextElementNode) executed on node COThe getFirstChild operation returns the first child FC of the context node CO.
Bahavior specified with base operations:- readCO
- useCOFCE
- readFC
- useFCPSE
Read and write sets for execution on CO:Read Set = CO FC COFCE FCPSE , Write Set = - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:-] on CO
