The getSuccessorsIterator provides an iterator over the set of successors,
i.e., deduplication is sometimes required (e.g. for MDPs).
We introduce here a SuccessorsIterator class that allows to make deduplication
optional, which may have benefits in performance. Additionally, SuccessorsIterator
implements a primitive OfInt iterator, which can avoid auto-boxing.
Subclasses of explicit.Model now have to provide an implementation for getSuccessors(int s),
getSuccessorsIterator(int s) is provided via a default method that automatically
requests deduplication.
Subclasses of explicit.NondetModel now have to provide an implementation for getSuccessors(int s, int).,
getSuccessorsIterator(int s, int i) is provided via a default method that automatically
requests deduplication.
Adapt the existing subclasses of explicit.Model.
Provides additional default methods and removes unneeded specializations in sub-classes:
boolean isSuccessor(int s1, int s2)
boolean allSuccessorsInSet(int s, BitSet set)
boolean someSuccessorsInSet(int s, BitSet set)
boolean allSuccessorsMatch(int s, IntPredicate p)
boolean someSuccessorsMatch(int s, IntPredicate p)
and for NondetModel:
boolean allSuccessorsInSet(int s, int i, BitSet set)
boolean someSuccessorsInSet(int s, int i, BitSet set)
boolean allSuccessorsMatch(int s, int i, IntPredicate p)
boolean someSuccessorsMatch(int s, int i, IntPredicate p)

- keeps track of model, builds when needed
- takes care of explicit engine stuff too
* Changes to deadlock handling:
- new option for "fix deadlocks" (defaults to *true*) (and new switch -fixdl)
- consistent deadlock handling everywhere, incl. GUI and experiments
- changes to model-level deadlock storage (symbolic and explicit)
* Explicit engine added as true engine, also available from GUI
git-svn-id: https://www.prismmodelchecker.org/svn/prism/prism/trunk@4562 bbc10eb1-c90d-0410-af57-cb519fbb1720
* merge ModelSimple and ModelSparse as ModelExplicit
* add ModelSimple as separate interface
* created DTMCExplicit to capture some common methods for DTMC classes
* (still need to do same for other models)
git-svn-id: https://www.prismmodelchecker.org/svn/prism/prism/trunk@3514 bbc10eb1-c90d-0410-af57-cb519fbb1720
* removed some old rewards code from explicit models
* (and temporarily disabled a few things in PrismSTPGAbstractRefine accordingly)
* added method addActionLabelledChoice to MDPSimple
