Detailed Description

Contains the PetscTools class, and the TERMINATE and NEVER_REACHED macros. The macros are defined here (rather than Exception.hpp) because they rely on MPI functionality to operate correctly when running in parallel.

Definition in file PetscTools.hpp.

Define Documentation

#define EXIT_IF_PARALLEL if(PetscTools::IsParallel()){TS_TRACE("This test does not pass in parallel yet.");return;}

For use in tests that do not work when run in parallel.

Definition at line 51 of file PetscTools.hpp.

#define EXIT_IF_SEQUENTIAL if(PetscTools::IsSequential()){TS_TRACE("This test is not meant to be executed in sequential.");return;}

For use in tests that should ONLY be run in parallel.

Definition at line 53 of file PetscTools.hpp.

#define NEVER_REACHED PetscTools::Terminate("Should have been impossible to reach this line of code", __FILE__, __LINE__); exit(EXIT_FAILURE)

Use for control paths that will never be executed, just to make sure they aren't.

The exit statement at the end of NEVER_REACHED is not really needed but prevents g++ from complaining about uninitialised variables when you have code that looks like:

   RelativeTo::Value relative_to;
   switch (rPath.relative_to())
   {
       case cp::relative_to_type::cwd:
           relative_to = RelativeTo::CWD;
           break;
       case cp::relative_to_type::chaste_test_output:
           relative_to = RelativeTo::ChasteTestOutput;
           break;
       case cp::relative_to_type::chaste_source_root:
           relative_to = RelativeTo::ChasteSourceRoot;
           break;
       case cp::relative_to_type::absolute:
           relative_to = RelativeTo::Absolute;
           break;
       default:
           NEVER_REACHED;
           break;
   }

relative_to is considered potentially uninitialised in the default branch unless the compiler finds a exit, assert or throw statement.

#define TERMINATE ( message ) PetscTools::Terminate(message, __FILE__, __LINE__)

Terminate execution safely, even when running in parallel. Use for level 4 errors: execution cannot continue from this point and hence should be terminated (even when running with NDEBUG).

Parameters:

message
