Detailed Description

The functions in this namespace are in connection with the Assert and AssertThrow mechanism but are solely for internal purposes and are not for use outside the exception handling and throwing mechanism.

Enumeration Type Documentation

enum deal_II_exceptions::internals::ExceptionHandling

An enum describing how to treat an exception in issue_error.

Enumerator
abort_on_exception	Abort the program by calling std::abort unless deal_II_exceptions::disable_abort_on_exception has been called: in that case the program will throw an exception.
throw_on_exception	Throw the exception normally.
abort_nothrow_on_exception	Call std::abort as long as deal_II_exceptions::disable_abort_on_exception has not been called: if it has, then just print a description of the exception to deallog.

Function Documentation

void deal_II_exceptions::internals::abort

(

const ExceptionBase &

exc

)

Conditionally abort the program.

Depending on whether deal_II_exceptions::disable_abort_on_exception was called, this function either aborts the program flow by printing the error message provided by exc and calling std::abort(), or throws exc instead.

Definition at line 468 of file exceptions.cc.

template<class ExceptionType >

void deal_II_exceptions::internals::issue_error_noreturn	(	ExceptionHandling	handling,
		const char *	file,
		int	line,
		const char *	function,
		const char *	cond,
		const char *	exc_name,
		ExceptionType	e
	)

This routine does the main work for the exception generation mechanism used in the Assert and AssertThrow macros: as the name implies, this function either ends with a call to abort or throwing an exception.

The actual exception object (the last argument) is typically an unnamed object created in place; because we modify it, we can't take it by const reference, and temporaries don't bind to non-const references. So take it by value (=copy it) with a templated type to avoid slicing – the performance implications are pretty minimal anyway.

ExceptionBase

Definition at line 1132 of file exceptions.h.

void deal_II_exceptions::internals::do_issue_error_nothrow ( const ExceptionBase &  e )

noexcept

Internal function that does the work of issue_error_nothrow.

Definition at line 452 of file exceptions.cc.

template<class ExceptionType >

void deal_II_exceptions::internals::issue_error_nothrow ( ExceptionHandling  , const char *  file, int  line, const char *  function, const char *  cond, const char *  exc_name, ExceptionType  e  )

noexcept

Exception generation mechanism in case we must not throw.

ExceptionBase

Note

This function is defined with a template for the same reasons as issue_error_noreturn().

Definition at line 1172 of file exceptions.h.

std::string deal_II_exceptions::internals::get_cusparse_error_string

(

const cusparseStatus_t

error_code

)

Return a string given an error code. This is similar to the cudaGetErrorString function but there is no equivalent function for cuSPARSE.

Definition at line 481 of file exceptions.cc.

std::string deal_II_exceptions::internals::get_cusolver_error_string

(

const cusolverStatus_t

error_code

)

Return a string given an error code. This is similar to the cudaGetErrorString function but there is no equivalent function for cuSOLVER.
