Detailed Description

Base of exceptions used in Flow123d.

We use boost::exception as parent in order to allow passing some data through the exception object from the throw point to the catch point. See DECLARE_EXCEPTION macro for usage.

When deriving particular exceptions always use virtual inheritance:

struct my_exception : virtual ExceptionBase {};

Constructor & Destructor Documentation

ExceptionBase() [1/2]

ExceptionBase::ExceptionBase

(

)

Default constructor, just calls fill_stacktrace().

Definition at line 25 of file exceptions.cc.

ExceptionBase() [2/2]

ExceptionBase::ExceptionBase

(

const ExceptionBase &

other

)

Copy constructor, performs deep copy of stacktrace.

Definition at line 31 of file exceptions.cc.

~ExceptionBase()

ExceptionBase::~ExceptionBase ( ) throw ( )

virtual

Destructor, possibly free stacktrace.

Definition at line 37 of file exceptions.cc.

Member Function Documentation

form_message()

std::ostringstream & ExceptionBase::form_message ( std::ostringstream &  converter ) const

protectedvirtual

Method for output the exception message. Implements composition of complex message including diagnostic informations and stack trace.

Reimplemented in feal::Exc_assert, and Input::Exception.

Definition at line 101 of file exceptions.cc.

Here is the caller graph for this function:

print_info()

virtual void ExceptionBase::print_info ( std::ostringstream &  out ) const

pure virtual

Purely virtual method, that should be implemented by descendants. Prints specific error message into stream out. In particular you can use macros DECLARE_EXCEPTION or DECLARE_INPUT_EXCEPTION for easy declarations.

Implemented in feal::Exc_assert, and ExcArmadillo.

Here is the caller graph for this function:

print_stacktrace()

void ExceptionBase::print_stacktrace

(

std::ostream &

out

)

const

Prints formated stacktrace into given stream out.

Definition at line 42 of file exceptions.cc.

Here is the caller graph for this function:

what()

const char * ExceptionBase::what	(		)	const
throw	(
	)

Overloaded method for output the exception message if it is not catched. Creates envelope of form_message method. Should not be overloded in descendant classes. Use form_message instead.

Definition at line 47 of file exceptions.cc.

Here is the caller graph for this function:

what_type_msg()

std::string ExceptionBase::what_type_msg ( ) const

protectedvirtual

Return type of message ("Program error" for this class). Can be override in descendants.

Reimplemented in feal::Exc_assert.

Definition at line 96 of file exceptions.cc.

Here is the caller graph for this function:

Member Data Documentation

frames_to_cut_

std::vector<std::string> ExceptionBase::frames_to_cut_

protected

Stacktrace frames, which will be cut, see StackTrace::print method.

Definition at line 109 of file exceptions.hh.

stack_trace_

StackTrace ExceptionBase::stack_trace_

protected

Stacktrace of exception.
