Test Case taDOM2/17-taDOM2-25-NS

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 prependChild(contextElementNode, childType, childValue) executed on node NS

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.

Bahavior specified with base operations:

readCO
modifyCOFCE
modifyFCPSE

Read and write sets for execution on NS:

Read Set = NS , Write Set =

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