Test Case taDOM3+/17-taDOM3+-8-CH

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 getLastChild(contextElementNode) executed on node CH

The getLastChild operation returns the last child LC of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCOLCE
  • readLC
  • useLCNSE

Read and write sets for execution on CH:

Read Set = CH DC CHLCE DCNSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:ER] on CH
  • LockRequest[node=LC,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on CH

Operations must be compatible
