Test Case taDOM2+/24-taDOM2+-7-AC

taDOM2+ 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. 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 appended 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 getFirstChild(contextElementNode) executed on node AC

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 AC:

Read Set = AC , Write Set =

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

Operations must be compatible

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