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::ExceptionBase ( )

Default constructor.

Definition at line 70 of file

ExceptionBase::ExceptionBase ( const ExceptionBase exc)

Copy constructor.

Definition at line 89 of file

ExceptionBase::~ExceptionBase ( )


Definition at line 108 of file

Member Function Documentation

ExceptionBase ExceptionBase::operator= ( const ExceptionBase )

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

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 116 of file

const char * ExceptionBase::what ( ) const

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

Definition at line 138 of file

const char * ExceptionBase::get_exc_name ( ) const

Get exception name.

Definition at line 160 of file

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

Print out the general part of the error information.

Definition at line 167 of file

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

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 199 of file

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 206 of file

void ExceptionBase::generate_message ( ) const

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

Definition at line 296 of file

Member Data Documentation

const char* ExceptionBase::file

Name of the file this exception happens in.

Definition at line 114 of file exceptions.h.

unsigned int ExceptionBase::line

Line number in this file.

Definition at line 119 of file exceptions.h.

const char* ExceptionBase::function

Name of the function, pretty printed.

Definition at line 124 of file exceptions.h.

const char* ExceptionBase::cond

The violated condition, as a string.

Definition at line 129 of file exceptions.h.

const char* ExceptionBase::exc

Name of the exception and call sequence.

Definition at line 134 of file exceptions.h.

char** ExceptionBase::stacktrace

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

Definition at line 140 of file exceptions.h.

int ExceptionBase::n_stacktrace_frames

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

Definition at line 146 of file exceptions.h.

void* ExceptionBase::raw_stacktrace[25]

array of pointers that contains the raw stack trace

Definition at line 152 of file exceptions.h.

std::string ExceptionBase::what_str

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

Definition at line 165 of file exceptions.h.
