Use enum fields to store the delimiters instead of the map.
Add some more comments to alert the user that proper quoting (for HTML labels) might be necessary.
Graphviz implements a subset of HTML that can be used in node and edge
labels (see https://graphviz.gitlab.io/_pages/doc/info/shapes.html#html
for a description of the subset) as an alternative to the plain-text
default style. The HTML-like style uses different attribute value
delimiters (<>) to the plain text style (""), but the latter is
hardcoded in explicit.graphviz.Decoration. The line delimiters also
differ (<br/> and \n respectively).
Provide support for both plain text and HTML-like labels in Decorator;
the label type can be changed by calling setLabelType() before appending
any label content via labelAddBelow() or labelAddAbove().
Previously, the flags for interval/topological iteration and
for Pmax-quotienting would not be initialised if the ModelChecker
was constructed directly.
As noted in #68, the javah tool has been removed in JDK10. Here, we switch to the new way of generating the JNI .h files, using the -h option of the regular javac compiler.
We have to adapt all Makefiles (not only those in directories that contain classes with native methods), as javac compiles all required classes (and generates their JNI headers) beyond the directory with the Makefile.
The .h files generated by javac -h had a different naming scheme, now there is a prefix for the package name. To avoid having to touch all the #includes, we generate the new .h files in prism/include/jni and provide legacy headers in the old location and with the old name, forwarding the the corresponding new header. In the future, at an appropriate moment, those legacy headers can be removed and replace with direct includes.
Currently, there is a post-processing step on Windows: After the .h file is generated, dos2unix is called to replace the Windows CRLF line endings. Otherwise, the generated headers show up as changed files in version control. As now there are no special targets for the generation of the .h files anymore, we move to a global post-processing step and call dos2unix on prism/include/jni/*.h at the end of building.
During model exploration of a CTMC, when using fast adaptive uniformisation,
only the last part of an update (rate & successor state) is used, as the
indexing of the outgoing transitions is buggy.
We now store all outgoing transitions and handle the case of multiple
choices/enabled commands in the CTMC.
+ two test cases
(addresses #72)
If the desired accuracy is to small, the naive weight computation can run
into an infinite loop, as floating point precision / rounding leads to
non-termination of the loop.
To partially address this, we move the accuracy check up, so that it
is also applied in the case of the 'naive' computation. This should make
it much less likely to run into this in practice.
For a full fix, we'd either need to check for non-progress in the loop
or do an analysis that the floating-point precision of double always
suffices for the remaining allowed input values.
This allows storage of BigRational values in StateValues / Values vectors, e.g.,
to store constants that have been evaluated exactly.
TypeDouble.castValueTo now returns a Number instead of a Double, requiring the use
of the doubleValue() method in several places where the value is evaluated using
double arithmetic.
To guarantee convergence, the power method requires the precomputation
P = (Q * deltaT + I)

The action object attached to a transition can be null (internal action), leading to a null pointer
exception when trying to call the toString method.
