This uses a new type of ExpressionFilter with op type "store",
rather than setting a boolean flag on existing filter objects.
Includes two test-cases showing examples where the old code failed.
This cleans up and refactors the iteration over state variable
valuation/value pairs via StateValues. In particular StateValuesMTBDD
learns how to do non-sparse printing.
Furthermore, it
* introduces generic "iterate" and "iterateFiltered"
methods for iterating over the state/values, calling a
StateAndValueConsumer object
* provides a StateAndValueConsumer implementation (StateAndValuePrinter)
that supports printing in the various output styles supported by PRISM
* cleans up the convenience "print" method using default methods in StateValues
* activates the MTBDD engine for one -exportvector based test
Note: Previously, in the StateValuesMTBDD iteration steps, the int[]
array with the current values represented the increments to be added
to the low values of state variables, with the addition
value = low + a[i]
happening on output. Now, we initialise the array with low, i.e.,
the values in the array correspond to the actual variable values.
Exports the value of a model checked property for all states as a vector.
If <file> is "stdout", this is displayed to the log instead of a file.
Currently, only works for a single property: if there is more than one,
then the file gets overwritten each time a property is checked.
Also fixes a bug in the underlying mechanism for storing results vectors
in the explicit engine (within Results objects).
