This graph shows which files directly or indirectly include this file:

Classes
class	isc::BadValue
	A generic exception that is thrown if a parameter given to a method is considered invalid in that context. More...

class	isc::Exception
	This is a base class for exceptions thrown from the DNS library module. More...

class	isc::InvalidOperation
	A generic exception that is thrown if a function is called in a prohibited way. More...

class	isc::InvalidParameter
	A generic exception that is thrown if a parameter given to a method or function is considered invalid and no other specific exceptions are suitable to describe the error. More...

class	isc::MultiThreadingInvalidOperation
	Exception thrown when a worker thread is trying to stop or pause the respective thread pool (which would result in a dead-lock). More...

class	isc::NotFound
	A generic exception that is thrown when an object can not be found. More...

class	isc::NotImplemented
	A generic exception that is thrown when a function is not implemented. More...

class	isc::OutOfRange
	A generic exception that is thrown if a parameter given to a method would refer to or modify out-of-range data. More...

class	isc::Unexpected
	A generic exception that is thrown when an unexpected error condition occurs. More...

Namespaces
namespace	isc
	Defines the logger used by the top-level component of kea-lfc.

Macros
#define	isc_throw(type, stream)
	A shortcut macro to insert known values into exception arguments.

#define	isc_throw_1(type, stream, param1)
	Similar as isc_throw, but allows the exception to have one additional parameter (the stream/text goes first)

#define	isc_throw_2(type, stream, param1, param2)
	Similar as isc_throw, but allows the exception to have two additional parameters (the stream/text goes first)

#define	isc_throw_3(type, stream, param1, param2, param3)
	Similar as isc_throw, but allows the exception to have three additional parameters (the stream/text goes first)

#define	isc_throw_4(type, stream, param1, param2, param3, param4)
	Similar as isc_throw, but allows the exception to have four additional parameters (the stream/text goes first)

Macro Definition Documentation

◆ isc_throw

#define isc_throw	(		type,
			stream )

Value:

    do { \
        std::ostringstream oss__; \
        oss__ << stream; \
        throw type(__FILE__, __LINE__, oss__.str().c_str()); \
    } while (1)

A shortcut macro to insert known values into exception arguments.

It allows the stream argument to be part of a statement using an ostream object and its operator<<. For example,

int x = 10;

isc_throw(SomeException, "Error happened, parameter: " << x);

isc_throw

#define isc_throw(type, stream)

A shortcut macro to insert known values into exception arguments.

Definition exceptions/exceptions.h:210

will throw an exception of class SomeException whose what string will be "Error happened, parameter: 10".

Note: the stream related operations or creation of the exception object may itself throw an exception (specifically std::bad_alloc). Even though it should be very rare, we may have to address this issue later.

Note: in general we hate macros and avoid using it in the code. This is one of few exceptions to that policy. inline functions cannot be used for embedding __FILE__ and __LINE__. This is the main reason why this is defined as a macro. The convenience for the ostream is a secondary purpose (if that were the only possible reason we should rather avoid using a macro).

◆ isc_throw_1

#define isc_throw_1	(	type,
		stream,
		param1 )

Value:

    do { \
        std::ostringstream oss__; \
        oss__ << stream; \
        throw type(__FILE__, __LINE__, oss__.str().c_str(), param1); \
    } while (1)

Similar as isc_throw, but allows the exception to have one additional parameter (the stream/text goes first)

◆ isc_throw_2

#define isc_throw_2	(	type,
		stream,
		param1,
		param2 )

        std::ostringstream oss__; \
        oss__ << stream; \
        throw type(__FILE__, __LINE__, oss__.str().c_str(), param1, param2); \
    } while (1)

Similar as isc_throw, but allows the exception to have two additional parameters (the stream/text goes first)

◆ isc_throw_3

#define isc_throw_3	(	type,
		stream,
		param1,

Value:

    do { \
        std::ostringstream oss__; \
        oss__ << stream; \
        throw type(__FILE__, __LINE__, oss__.str().c_str(), param1, param2,\
                   param3); \
    } while (1)

Similar as isc_throw, but allows the exception to have three additional parameters (the stream/text goes first)

        std::ostringstream oss__; \
        oss__ << stream; \
        throw type(__FILE__, __LINE__, oss__.str().c_str(), param1, param2,\
                   param3, param4); \
