Test Case taDOM3/29-taDOM3-2-NS

taDOM3 Lock Requests of executed Operation insertAfter(contextNode, siblingType, siblingValue) returns Node

The insertAfter operation is executed on the context element node CO and inserts a new next sibling node after the context node CO. There already exists a next sibling and the inserted new sibling node is returned.

Behavior specified with base operations:

  • readCO
  • modifyCONSE
  • modifyNSPSE
Read Set = CO , Write Set = CONSE NSPSE
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:EX,FCE:-,LCE:-]
  • LockRequest[node=NS,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:-,LCE:-]

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

The getPrevSibling operation returns the previous sibling node PS of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • readPS
  • usePSNSE

Read and write sets for execution on NS:

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

Operations must be incompatible
