Test Case taDOM2/9-taDOM2-23-PS

taDOM2 Lock Requests of executed Operation getLastChild(contextElementNode) returns null value

The getLastChild operation returns null because the context node CO does not have any child nodes.

Behavior specified with base operations:

  • readCO
  • useCOLCE
  • useCOFCE
Read Set = CO COFCE COLCE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]

taDOM2 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node PS

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOLCE
  • modifyLCNSE

Read and write sets for execution on PS:

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

Operations must be compatible
