Detailed Description

Contains the Exception class, along with some macros that are widely used throughout the code.

Definition in file Exception.hpp.

Macro Definition Documentation

#define ABORT_IF_NON0	(	cmd,
		arg
	)

Value:

{ \
    std::string _arg(arg);        \
    int ret = cmd(_arg.c_str());  \
    ABORT_IF_NON0_WITH_MSG(ret, "Error executing command: " #cmd "(" + _arg + ")") \
    }

Note: This macro is deprecated, and no longer used by core code.

Handy for calling functions like system which return non-zero on error. Terminate if an error occurs.

This macro should be used instead of EXPECT0 within blocks that are only executed by one process, but need to kill all processes if an error occurs.

Parameters

cmd	command to call
arg	its argument (will be converted to std::string)

Definition at line 287 of file Exception.hpp.

#define ABORT_IF_NON0_WITH_MSG	(	retcode,
		msg
	)

Value:

if (retcode != 0) {                          \
        TERMINATE(msg);                          \
    }

Note: This macro is deprecated, and no longer used by core code.

Handy for calling functions like system which return non-zero on error. Terminate if the return code is non-zero, printing a suitable message.

Parameters

retcode	command return code
msg	error message to display

Definition at line 270 of file Exception.hpp.

#define ABORT_IF_THROWS ( block )

Value:

try {                               \
        block;                          \
    } catch (const Exception& e) {      \
        TERMINATE(e.GetMessage());      \
    } catch (const std::exception &e) { \
        TERMINATE(e.what());            \
    } catch (...) {                     \
        TERMINATE("Unexpected exception thrown."); \
    }

Convenience function to convert an exception thrown by a single process into termination of the entire program.

Parameters

block the block of code to execute

Definition at line 225 of file Exception.hpp.

#define EXCEPT_IF_NOT ( test ) if (!(test)) EXCEPTION("Assertion tripped: " BOOST_PP_STRINGIZE(test))

Convenience macro for changing an assert into an exception - has the same calling semantics, but throws.

Parameters

test	the test that must always be true.

Definition at line 158 of file Exception.hpp.

#define EXCEPTION ( message )

Value:

do {                                             \
        std::stringstream msg_stream;                \
        msg_stream << message;                       \
        throw Exception(msg_stream.str(), __FILE__, __LINE__); \
    } while (false)

Convenience macro for throwing an exception, in order to add file and line info.

Parameters

message the error message to use, as a streamed expression

Definition at line 143 of file Exception.hpp.

#define EXPECT0	(	cmd,
		arg
	)

Value:

{      \
    std::string _arg(arg);       \
    int retcode = cmd(_arg.c_str()); \
    if (retcode != 0) {              \
        EXCEPTION("Error executing command: " #cmd "(" + _arg + ")"); \
    } }

Note: This macro is deprecated.

Handy for calling functions like system which return non-zero on error. Throws if an error occurs.

Note: DO NOT use this macro within an if (PetscTools::AmMaster) block, as then you'll get deadlock if an exception is thrown when running in parallel! (Unless the block is wrapped in a try-catch and exception replication handler.) Instead, use ABORT_IF_NON0.

Parameters

cmd	command to call
arg	its argument (will be converted to std::string)

Definition at line 254 of file Exception.hpp.

Referenced by PetscSetupUtils::CommonSetup(), and CellMLToSharedLibraryConverter::ConvertCellmlToSo().

#define EXPECT_NON0	(	cmd,
		arg
	)

Value:

{   \
    std::string _arg = (arg);     \
    int ret = cmd(_arg.c_str());  \
    if (ret == 0) {               \
        EXCEPTION("Command: " #cmd "(" + _arg + ") succeeded and it shouldn't have"); \
    } }

Note: This macro is deprecated, and no longer used by core code.

Handy for calling functions like system which return non-zero on error. This time we expect failure; throws if the command succeeds.

Parameters

cmd	command to call
arg	its argument (will be converted to std::string)

Definition at line 301 of file Exception.hpp.

#define IGNORE_RET	(	cmd,
		arg
	)

Value:

{   \
    std::string _arg = (arg);    \
    int ret = cmd(_arg.c_str()); \
    ret = ret;                   \
    }

Note: This macro is deprecated.

Handy for calling functions like system which return non-zero on error. This version ignores the return code, in case you don't care about errors for some reason...

Parameters

cmd	command to call
arg	its argument (will be converted to std::string)

Definition at line 316 of file Exception.hpp.

#define NEVER_REACHED TERMINATE("Should have been impossible to reach this line of code"); 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.

Definition at line 206 of file Exception.hpp.

#define TERMINATE ( message )

Value:

do {                                             \
        std::stringstream msg_stream;                \
        msg_stream << message;                       \
        Exception::Terminate(msg_stream.str(), __FILE__, __LINE__); \
    } while (false)

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 explanatory message

#define UNUSED_OPT ( var )

This is to cope with NDEBUG causing variables to not be used, when they are only used in assert()s.

Parameters

var	the "unused" variable
