Test Case taDOM3+/6-taDOM3+-23-NS

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 appendChild(contextElementNode, childType, childValue) executed on node NS

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Bahavior specified with base operations:

readCO
modifyCOLCE
modifyLCNSE

Read and write sets for execution on NS:

Read Set = NS , Write Set =

LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX] on NS
LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-] on NS

Operations must be compatible
