Test Case taDOM2/26-taDOM2-28-CO

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

The 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.

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 insertBefore(contextNode, siblingType, siblingValue) executed on node CO

The insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There does not exist a previous sibling, so the context element node was the first child of the parent node PA and the inserted new sibling node (the new first child of PA) is returned.

Bahavior specified with base operations:

readCO
modifyCOPSE
modifyPAFCE

Read and write sets for execution on CO:

Read Set = CO , Write Set = PAFCE COPSE

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