Detailed Description

Used to construct and throw a standard C++ exception. Inherits from std::exception.

Warning

Creates a backtrace, which introduces much overhead. Whenever possible, avoid constructing the exception until the exact line of where the error condition is detected or a neighboring line which is not separated by any functional code from the place where the error condition is detected.

Do not construct this exception unless it is going to be thrown

Constructor & Destructor Documentation

SpartaException() [1/2]

sparta::SpartaException::SpartaException

(

)

Construct a SpartaException object with empty reason.

Note

All other non-copy and non-move constructors must delegate to this constructor so that breakpoints can easily be placed on one symbol to catch sparta Exceptions

Reason can be populated later with the insertion operator.

SpartaException() [2/2]

sparta::SpartaException::SpartaException

(

const std::string &

reason

)

Construct a SpartaException object.

Parameters

reason

The reason for the exception

Note

Delegated to SpartaException so that debugger breakpoints may be more easily be placed.

Member Function Documentation

operator<<()

template<class T >

SpartaException & sparta::SpartaException::operator<< ( const T &  msg )

inline

Append additional information to the message.

Parameters

msg	The addition info

Returns

This exception object

Usage:

int bad_company = 4;
sparta::SpartaException e("Oh uh");
e << ": this is bad: " << bad_company;

or you can do this:

int bad_company = 4;
throw sparta::SpartaException e("Oh uh") << ": this is bad: " << bad_company;

but it's not as pretty.

rawReason()

std::string sparta::SpartaException::rawReason ( ) const

inline

Return the raw reason without file, line information.

Returns

The raw reason, no file information

Definition at line 111 of file SpartaException.hpp.

what()

const char * sparta::SpartaException::what ( ) const
