Test Case taDOM2/32-taDOM2-26-LC

taDOM2 Lock Requests of executed Operation deleteNode(contextNode) returns nothing

The deleteNode operation is executed on the context element node CO and deletes the context node. Thereby, the context node is the first child of its parent node.

Behavior specified with base operations:

  • modifyPAFCE
  • modifyNSPSE
  • writeCO
  • writeFC
  • writeCH
  • writeLC
  • writeDC
Read Set = , Write Set = CO FC CH LC DC CA AS AX XS PAFCE NSPSE
  • LockRequest[node=CO,lock:SX,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=NS,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:EX,LCE:-]

taDOM2 Lock Requests of checked Operation prependChild(contextElementNode, childType, childValue) executed on node LC

The prependChild operation is executed on the context element node CO and prepends a new child. The context element node CO has still no child nodes before this operation. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on LC:

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

Operations must be incompatible
