Test Case taDOM2/25-taDOM2-34-AC

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 to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.

Behavior specified with base operations:

readCO
modifyCOFCE
modifyFCPSE

Read Set = CO , Write Set = COFCE FCPSE

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

taDOM2 Lock Requests of checked Operation deleteNode(contextNode) executed on node AC

The deleteNode operation is executed on the context element node CO and deletes the context node. Thereby, the context node is the only child of its parent node.

Bahavior specified with base operations:

modifyPAFCE
modifyPALCE
writeCO
writeFC
writeCH
writeLC
writeDC

Read and write sets for execution on AC:

Read Set = , Write Set = AC PA PS CO CS NS FC CH LC DC CA AS AX XS
