Test Case taDOM2/0-taDOM2-3-LC

taDOM2 Lock Requests of executed Operation getNode(DeweyID) returns Node

The getNode operation returns the context node CO addressed by the passed deweyID.

Behavior specified with base operations:

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

taDOM2 Lock Requests of checked Operation getPrevSibling(contextNode) executed on node LC

The getPrevSibling operation returns null because the context node CO is the first child of parent node PA and no previous sibling node PS exists.

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • usePAFCE

Read and write sets for execution on LC:

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

Operations must be compatible
