Detailed Description

usefull utility classes and functions

The KK namespace contains usefull stuff used frequently by K.K. Chand.

Typedef Documentation

typedef double KK::real

change the value of this typedef to get single/double precision

Function Documentation

long int KK::acquire_gid

(

)

acquire a "global" id, this will be used interally by KK::sptr

Referenced by KK::sptr< T >::sptr().

template<class E , class B >

void KK::Assert ( B  assertion, std::string  s = ""  )

inline

an assertion that can be used with derivations of the Err class. similar to Stroustroup "The C++ Programming Language, 3rd Ed., SS 24.3.7.2

Parameters

assertion	the boolean assertion
s	a string that holds information in case of failure (added to the exception) note that the assertions only do something when KK_DEBUG is defined

References E, and s.

Referenced by KK::sptr< T >::sptr().

template<class E , class B >

void KK::Assert ( B  assertion, E  exception  )

inline

simple assertion throwing a user defined exception instance

an assertion that can be used with derivations of the Err class. similar to Stroustroup "The C++ Programming Language, 3rd Ed., SS 24.3.7.2

Parameters

assertion	the boolean assertion
exception	the exception to be thrown in the case of failure. note that the assertions only do something when KK_DEBUG is defined

template<class E , class B >

void KK::AssertAlways ( B  assertion, std::string  s = ""  )

inline

an assertion that can be used with derivations of the Err class. similar to Stroustroup "The C++ Programming Language, 3rd Ed., SS 24.3.7.2

Parameters

assertion	the boolean assertion
s	a string that holds information in case of failure (added to the exception) note that the assertions always do something, even when KK_DEBUG is not defined

References E, and s.

template<class E , class B >

void KK::AssertAlways ( B  assertion, E  exception  )

inline

simple assertion throwing a user defined exception instance

an assertion that can be used with derivations of the Err class. similar to Stroustroup "The C++ Programming Language, 3rd Ed., SS 24.3.7.2

Parameters

assertion	the boolean assertion
exception	the exception to be thrown in the case of failure. note that this assertion is ALWAYS on, even if KK_DEBUG is defined!
