Test Case taDOM3+/23-taDOM3+-4-FC

taDOM3+ Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns Node

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Behavior specified with base operations:

readCO
modifyCOLCE
modifyLCNSE

Read Set = CO , Write Set = COLCE LCNSE

LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX]
LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation getNextSibling(contextNode) executed on node FC

The getNextSibling operation returns the next sibling node NS of the context node CO.

Bahavior specified with base operations:

readCO
useCONSE
readNS
useNSPSE

Read and write sets for execution on FC:

Read Set = FC CH FCNSE CHPSE , Write Set =

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

Operations must be compatible

Check	Existing LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX] with Requested LockRequest[node=CO,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on FC	Requested lock IR on AC compatible to existing lock IX. Requested lock IR on PA compatible to existing lock IX. Requested lock IR on CO compatible to existing lock NRCX.	Compatible
Check	Existing LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX] with Requested LockRequest[node=NS,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on FC	Requested lock IR on AC compatible to existing lock IX. Requested lock IR on PA compatible to existing lock IX. Requested lock IR on CO compatible to existing lock NRCX.	Compatible
