Test Case taDOM2/7-taDOM2-17-COtaDOM2 Lock Requests of executed Operation getFirstChild(contextElementNode) returns null valueThe getFirstChild operation returns null because the context node CO does not have any child nodes.
Behavior specified with base operations:Read Set = CO COFCE COLCE , Write Set = - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER]
- LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
taDOM2 Lock Requests of checked Operation setValue(contextElementNode, valueString) executed on node COThe setValue operation executed on the context element node CO returns the modified context element itself. In taDOM2(+) the CX lock on PA must be requested additionally in order to prevent an execution of the getChildNodes() method on the parent node.
Bahavior specified with base operations:Read and write sets for execution on CO:Read Set = , Write Set = CO - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on CO
- LockRequest[node=CN,lock:SX,PSE:-,NSE:-,FCE:-,LCE:-] on CO
- LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:-,LCE:-] on CO
Operations must be incompatibleCheck | Existing LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER] with Requested LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on CO | Requested lock IR on AC compatible to existing lock IR.
