|
* Class for an abstract formula tree with a R (reward) operator node over a reward interval as root.
|
|

|
|
* Has a reward path formula as sub formula/tree.
|
|
*
|
|
* @par Semantics
|
|
* The formula holds iff the reward of the reward path formula is inside the bounds
|
|
* specified in this operator
|
|
*
|
|
* The subtree is seen as part of the object and deleted with it
|
|
* (this behavior can be prevented by setting them to NULL before deletion)
