  Test Case taDOM3/26-taDOM3-22-CO
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. 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:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]
taDOM3 Lock Requests of checked Operation renameAttribute(contextElementNode, ctxAttrOldNameString, ctxAttrNewNameString) executed on node COThe renameAttribute operation is executed on the context element node CO and renames the context attribute CA with the passed old name to the passed new name. In taDOM2(+) the CX lock on AR must be requested additionally in order to prevent an execution of the getAttributes() method on the context node. The operation returns the rename attribute node CA.
Bahavior specified with base operations:Read and write sets for execution on CO:Read Set = CO , Write Set = CA - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on CO
- LockRequest[node=CA,lock:NX,PSE:-,NSE:-,FCE:-,LCE:-] on CO
