Test Case taDOM2/23-taDOM2-9-NS

taDOM2 Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns Node

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.

Behavior specified with base operations:

  • readCO
  • modifyCOLCE
  • modifyLCNSE
Read Set = CO , Write Set = COLCE LCNSE
  • LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:-,LCE:EX]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]

taDOM2 Lock Requests of checked Operation getLastChild(contextElementNode) executed on node NS

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

Bahavior specified with base operations:

  • readCO
  • useCOLCE
  • useCOFCE

Read and write sets for execution on NS:

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

Operations must be compatible
