Test Case taDOM2/25-taDOM2-7-FC

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 getFirstChild(contextElementNode) executed on node FC

The getFirstChild operation returns null because the context node CO does not have any child nodes.

Bahavior specified with base operations:

readCO
useCOFCE
useCOLCE

Read and write sets for execution on FC:

Read Set = FC FCFCE FCLCE , Write Set =

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

Operations must be compatible
