Detailed Description

template<typename T_, bool IsDynamic_, T_ StaticValue_ = T_()>
class Tomographer::Tools::StaticOrDynamic< T_, IsDynamic_, StaticValue_ >

A type which stores a value possibly known at compile-time.

This is an implementation inspired by Eigen's mechanism of compile-time known matrix/vector sizes.

This class declares a private member property which stores a dynamic value given to the constructor, except if a value was already given as template parameter in which case we take for granted that this value will always be the one we want at runtime.

Template Parameters

T_	the type of the value to store.
IsDynamic_	whether to store a dynamical value, or to store the static, fixed compile-time value.
StaticValue_	to store at compile-time. This value will be ignored if IsDynamic is false.

Constructor & Destructor Documentation

StaticOrDynamic()

template<typename T_, bool IsDynamic_, T_ StaticValue_ = T_()>

Tomographer::Tools::StaticOrDynamic< T_, IsDynamic_, StaticValue_ >::StaticOrDynamic ( T  val )

inlineexplicit

Constructor with an explicit value.

The value val must equal the compile-time fixed value, if any, or you'll get an assert failure.

Member Function Documentation

operator()()

template<typename T_, bool IsDynamic_, T_ StaticValue_ = T_()>

T Tomographer::Tools::StaticOrDynamic< T_, IsDynamic_, StaticValue_ >::operator() ( ) const

inline

Get the value stored.

The same call syntax works both for dynamic and compile-time storage.

Definition at line 188 of file cxxutil.h.

value()

template<typename T_, bool IsDynamic_, T_ StaticValue_ = T_()>

T Tomographer::Tools::StaticOrDynamic< T_, IsDynamic_, StaticValue_ >::value ( ) const

inline

Get the value stored.

The same call syntax works both for dynamic and compile-time storage.
