Test Case taDOM3+/25-taDOM3+-20-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 setAttribute(contextElementNode, ctxAttrNameString, valueString) executed on node NS

The setAttribute operation is executed on the context element node CO and sets a new value of the context attribute node CA. The named context attribute already exists and the operation returns the value node AS.

Bahavior specified with base operations:

  • readCO
  • readCA
  • writeAS

Read and write sets for execution on NS:

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

Operations must be compatible
