Test Case taDOM2/17-taDOM2-26-PS

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 PS

The prependChild operation is executed on the context element node CO and prepends a new child. The context element node CO has still no child nodes before this operation. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on PS:

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

Operations must be compatible
