Test Case taDOM3+/25-taDOM3+-17-NS

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

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.

Behavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyFCPSE
Read Set = CO , Write Set = COFCE FCPSE
  • LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:-]
  • LockRequest[node=FC,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation setValue(contextElementNode, valueString) executed on node NS

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.

Bahavior specified with base operations:

  • writeCO

Read and write sets for execution on NS:

Read Set = , Write Set = NS
  • LockRequest[node=CO,lock:NX,PSE:-,NSE:-,FCE:-,LCE:-] on NS

Operations must be compatible
