Test Case taDOM2+/24-taDOM2+-23-CO

taDOM2+ Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns Node

The appendChild operation is executed on the context element node CO and appends a new child. The context element node CO has still no child nodes before this operation. 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 now only child) is returned.

Behavior specified with base operations:

readCO
modifyCOFCE
modifyCOLCE

Read Set = CO , Write Set = COFCE COLCE

LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:EX]
LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]

taDOM2+ Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node CO

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 CO:

Read Set = CO , Write Set = COLCE LCNSE

LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:-,LCE:EX] on CO
LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on CO
LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-] on CO

Operations must be incompatible
