Test Case taDOM3+/23-taDOM3+-4-NS

taDOM3+ 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:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX]
  • LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation getNextSibling(contextNode) executed on node NS

The getNextSibling operation returns the next sibling node NS of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCONSE
  • readNS
  • useNSPSE

Read and write sets for execution on NS:

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

Operations must be compatible
