* @brief
|
|
* Class for an Abstract (path) formula tree with a SteadyStateOperator node as root.
|
|
*
|
|
* Has two formulas as sub formulas/trees.
|
|
*
|
|
* @par Semantics
|
|
* The formula holds iff \e child holds SteadyStateOperator step, \e child holds
|
|
*
|
|
* The subtree is seen as part of the object and deleted with the object
|
|
* (this behavior can be prevented by setting them to NULL before deletion)
