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 96 of file exceptions.cc.

◆ ExceptionBase() [2/2]

ExceptionBase::ExceptionBase ( const ExceptionBase exc)

Copy constructor.

Definition at line 112 of file exceptions.cc.

◆ ~ExceptionBase()

virtual ExceptionBase::~ExceptionBase ( )
overridevirtualdefaultnoexcept

Destructor.

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 135 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 160 of file exceptions.cc.

◆ get_exc_name()

const char * ExceptionBase::get_exc_name ( ) const

Get exception name.

Definition at line 172 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 180 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, internal::NoPermutation< T >, LACExceptions::ExcPETScError, and SolverControl::NoConvergence.

Definition at line 232 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 240 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 341 of file exceptions.cc.

Member Data Documentation

const char* ExceptionBase::file
protected

Name of the file this exception happens in.

Definition at line 129 of file exceptions.h.

◆ line

unsigned int ExceptionBase::line
protected

Line number in this file.

Definition at line 134 of file exceptions.h.

◆ function

const char* ExceptionBase::function
protected

Name of the function, pretty printed.

Definition at line 139 of file exceptions.h.

◆ cond

const char* ExceptionBase::cond
protected

The violated condition, as a string.

Definition at line 144 of file exceptions.h.

◆ exc

const char* ExceptionBase::exc
protected

Name of the exception and call sequence.

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 following 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()
