11 years ago
dehnert 92ee6187fa Added more query methods to expressions. SparseMatrix now keeps track of non zero entries and models show correct number of transitions by referring to nonzero entries rather than all entries in the matrix.

dehnert a0df98a6eb Removed unnecessary virtual keyword in Expression class.
11 years ago
dehnert 219af9b43b Removed constants from expressions. Even though PRISM has the concept of constants and variables, it currently makes no sense to distinguish them in our expression classes.

dehnert 3eb8f8e328 Bugfix: valuations now correctly store the given initial value for boolean variables.
11 years ago
dehnert 39ec9401ef Fixed the PrismParser so the exact format of PRISMs boolean expressions can now be parsed.
11 years ago
dehnert 63601e0b8a Calling getExpression on an undefined constant is now properly treated with an exception.

dehnert 6078e07476 First version of DD iterator; small test included.
11 years ago
PBerger 1d8ae9fc89 Fixed an issue with templated variadic template arguments (see http://stackoverflow.com/questions/23119273/use-a-templated-variadic-template-parameter-as-specialized-parameter for discussion)
