Detailed Description

template<typename T_, int Value>
class Tomographer::Tools::static_or_dynamic< T_, Value >

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.
Value	the (integer) value to store at compile-time. If this value is Eigen::Dynamic, then the value will be stored at runtime.

Constructor & Destructor Documentation

template<typename T_, int Value>

Tomographer::Tools::static_or_dynamic< T_, Value >::static_or_dynamic ( 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

template<typename T_, int Value>

T Tomographer::Tools::static_or_dynamic< T_, Value >::operator() ( ) const

inline

Get the value stored.

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