Use Case 25:

Node Operation prependChild(contextElementNode, childType, childValue)
returns Node

The prependChild operation is executed on the context element node CO and prepends a new child to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.
  • This operation can be executed on an element context node
  • This operation cannot be executed on an text context node

Operation behavior described with base operations:

  • readCO
  • modifyCOFCE
  • modifyFCPSE
Read Set = CO , Write Set = COFCE FCPSE

This operation can be executed on the following nodes:

  • AC
  • PA
  • PS
  • CO
  • NS
  • FC
  • CH
  • LC
  • DC

If this operation is executed the following nodes are existing:

  • AC
  • PA
  • PS
  • CO
  • NS
  • FC
  • CH
  • LC
  • DC
  • CA
  • AX
