Test Case taDOM2/17-taDOM2-23-LC

taDOM2 Lock Requests of executed Operation setValue(contextElementNode, valueString) returns Node

The 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.

Behavior specified with base operations:

writeCO

Read Set = , Write Set = CO

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

taDOM2 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node LC

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.

Bahavior specified with base operations:

readCO
modifyCOLCE
modifyLCNSE

Read and write sets for execution on LC:

Read Set = LC , Write Set = LCLCE DCNSE

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