Test Case taDOM3+/22-taDOM3+-24-FC

taDOM3+ Lock Requests of executed Operation renameAttribute(contextElementNode, ctxAttrOldNameString, ctxAttrNewNameString) returns Node

The renameAttribute operation is executed on the context element node CO and renames the context attribute CA with the passed old name to the passed new name. In taDOM2(+) the CX lock on AR must be requested additionally in order to prevent an execution of the getAttributes() method on the context node. The operation returns the rename attribute node CA.

Behavior specified with base operations:

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

taDOM3+ Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node FC

The appendChild operation is executed on the context element node CO and appends 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 appended child node (the now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on FC:

Read Set = FC , Write Set = FCFCE FCLCE
  • LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX] on FC

Operations must be compatible
