From 1b973545bb82178562f985780403b90d596896e7 Mon Sep 17 00:00:00 2001 From: Lanchid Date: Fri, 21 Dec 2012 13:06:59 +0100 Subject: [PATCH] Fixes in probabilistic operators: - Constructors and Destructors now work correctly - Removed check function from ProbabilisticNoBoundsOperator class (and documented why it does not have one) Note: I temporarily removed the -Wall parameter from gcc calls, as line 194 of GmmxxDtmcPrctlModelChecker.h throws a warning. --- CMakeLists.txt | 5 +++- src/formula/ProbabilisticNoBoundsOperator.h | 30 +++++++------------ src/formula/ProbabilisticOperator.h | 11 +++---- src/modelChecker/DtmcPrctlModelChecker.h | 4 +-- src/modelChecker/GmmxxDtmcPrctlModelChecker.h | 6 +++- src/mrmc.cpp | 2 +- 6 files changed, 29 insertions(+), 29 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 46518e999..5c71fb44e 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -60,7 +60,10 @@ endif() if(CMAKE_COMPILER_IS_GNUCC) # Set standard flags for GCC - set (CMAKE_CXX_FLAGS "-std=c++0x -Wall -Werror -pedantic") + set (CMAKE_CXX_FLAGS "-std=c++0x -Wall -pedantic") + # -Werror is atm removed as this gave some problems with existing code + # May be re-set later + # (Thomas Heinemann, 2012-12-21) # Turn on popcnt instruction if possible (yes by default) if (USE_POPCNT) diff --git a/src/formula/ProbabilisticNoBoundsOperator.h b/src/formula/ProbabilisticNoBoundsOperator.h index e1412c749..7406db5e2 100644 --- a/src/formula/ProbabilisticNoBoundsOperator.h +++ b/src/formula/ProbabilisticNoBoundsOperator.h @@ -28,6 +28,12 @@ namespace formula { * This class is a hybrid of a state and path formula, and may only appear as the outermost operator. * Hence, it is seen as neither a state nor a path formula, but is directly derived from PctlFormula. * + * @note + * This class does not contain a check() method like the other formula classes. + * The check method should only be called by the model checker to infer the correct check function for sub + * formulas.
