  Test Case taDOM3/25-taDOM3-7-DC
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 DCThe getFirstChild operation returns null because the context node CO does not have any child nodes.
