Detailed Description

This class is the base class for all exception classes. Do not use its methods and variables directly since the interface and mechanism may be subject to change. Rather create new exception classes using the DeclException macro family.

See the Exceptions and assertions module for more details on this class and what can be done with classes derived from it.

Constructor & Destructor Documentation

ExceptionBase() [1/2]

ExceptionBase::ExceptionBase

(

)

Default constructor.

Definition at line 79 of file exceptions.cc.

ExceptionBase() [2/2]

ExceptionBase::ExceptionBase

(

const ExceptionBase &

exc

)

Copy constructor.

Definition at line 96 of file exceptions.cc.

Member Function Documentation

operator=()

ExceptionBase ExceptionBase::operator= ( const ExceptionBase &  )

delete

Copy operator. This operator is deleted since exception objects are not copyable.

set_fields()

void ExceptionBase::set_fields	(	const char *	file,
		const int	line,
		const char *	function,
		const char *	cond,
		const char *	exc_name
	)

Set the file name and line of where the exception appeared as well as the violated condition and the name of the exception as a char pointer. This function also populates the stacktrace.

Definition at line 124 of file exceptions.cc.

what()

const char * ExceptionBase::what ( ) const

overridevirtualnoexcept

Override the standard function that returns the description of the error.

Definition at line 147 of file exceptions.cc.

get_exc_name()

const char * ExceptionBase::get_exc_name

(

)

const

Get exception name.

Definition at line 170 of file exceptions.cc.

print_exc_data()

void ExceptionBase::print_exc_data

(

std::ostream &

out

)

const

Print out the general part of the error information.

Definition at line 178 of file exceptions.cc.

print_info()

void ExceptionBase::print_info ( std::ostream &  out ) const

virtual

Print more specific information about the exception which occurred. Overload this function in your own exception classes.

Reimplemented in StandardExceptions::ExcMPI, SolverControl::NoConvergence, and LACExceptions::ExcPETScError.

Definition at line 210 of file exceptions.cc.

print_stack_trace()

void ExceptionBase::print_stack_trace

(

std::ostream &

out

)

const

Print a stacktrace, if one has been recorded previously, to the given stream.

Definition at line 218 of file exceptions.cc.

generate_message()

void ExceptionBase::generate_message ( ) const

private

Internal function that generates the c_string. Called by what().

Definition at line 307 of file exceptions.cc.

Member Data Documentation

file

const char* ExceptionBase::file

protected

Name of the file this exception happens in.

Definition at line 123 of file exceptions.h.

line

unsigned int ExceptionBase::line

protected

Line number in this file.

Definition at line 128 of file exceptions.h.

function

const char* ExceptionBase::function

protected

Name of the function, pretty printed.

Definition at line 133 of file exceptions.h.

cond

const char* ExceptionBase::cond

protected

The violated condition, as a string.

Definition at line 138 of file exceptions.h.

exc

const char* ExceptionBase::exc

protected

Name of the exception and call sequence.

Definition at line 143 of file exceptions.h.

stacktrace

char** ExceptionBase::stacktrace

mutableprotected

A backtrace to the position where the problem happened, if the system supports this.

Definition at line 149 of file exceptions.h.

n_stacktrace_frames

int ExceptionBase::n_stacktrace_frames

protected

The number of stacktrace frames that are stored in the previous variable. Zero if the system does not support stack traces.

Definition at line 155 of file exceptions.h.

raw_stacktrace

void* ExceptionBase::raw_stacktrace[25]

protected

array of pointers that contains the raw stack trace

Definition at line 161 of file exceptions.h.

what_str

std::string ExceptionBase::what_str

mutableprivate

A pointer to the c_string that will be printed by what(). It is populated by generate_message()

Definition at line 175 of file exceptions.h.
