Test Case taDOM3/17-taDOM3-1-CO

taDOM3 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:NX,PSE:-,NSE:-,FCE:-,LCE:-]

taDOM3 Lock Requests of checked Operation getParentNode(contextNode) executed on node CO

The getParentNode operation returns the parent node PA of the context node CO.

Bahavior specified with base operations:

  • readCO
  • readPA

Read and write sets for execution on CO:

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

Operations must be incompatible
