Test Case taDOM2/7-taDOM2-26-PS
taDOM2 Lock Requests of executed Operation getFirstChild(contextElementNode) returns null valueThe getFirstChild operation returns null because the context node CO does not have any child nodes.
Behavior specified with base operations:Read Set = CO COFCE COLCE , Write Set = - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER]
- LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
taDOM2 Lock Requests of checked Operation prependChild(contextElementNode, childType, childValue) executed on node PSThe prependChild operation is executed on the context element node CO and prepends 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 prepended child node (the now only child) is returned.
Bahavior specified with base operations:- readCO
- modifyCOFCE
- modifyCOLCE
Read and write sets for execution on PS:Read Set = PS , Write Set = - LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:EX] on PS
- LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PS
