jevois::ValidValuesSpecBase< T > Class Template Reference

#include <jevois/Component/ValidValuesSpec.H>

template<typename T>
class jevois::ValidValuesSpecBase< T >

Base class for specifying a set of valid values for a type.

Note when defining new derived valid values specs: make sure you define operator<<() and also that the copy constructor works as intended (which means that you may have to define it explicitly if your data members are complicated).

Definition at line 44 of file ValidValuesSpec.H.

Constructor & Destructor Documentation

ValidValuesSpecBase()

template<typename T >

jevois::ValidValuesSpecBase< T >::ValidValuesSpecBase ( )

explicit

Construct, for the base class this is a no-op.

Note that we make the constructor explicit otherwise we get false hits against strings and what not in our operator<< defined on various ValidValueSpec derivatives.

~ValidValuesSpecBase()

template<typename T >

virtual jevois::ValidValuesSpecBase< T >::~ValidValuesSpecBase ( )

virtual

Destructor.

Member Function Documentation

checkValueValidity()

template<typename T >

virtual bool jevois::ValidValuesSpecBase< T >::checkValueValidity ( T const &  val ) const

pure virtual

Check whether a proposed value is valid, return true if it is.

Implemented in jevois::ValidValuesSpecNone< T >, jevois::ValidValuesSpecList< T >, jevois::ValidValuesSpecRange< T >, jevois::ValidValuesSpecStepRange< T >, and jevois::ValidValuesSpecRegex< T >.

str()

template<typename T >

virtual std::string const jevois::ValidValuesSpecBase< T >::str ( ) const

pure virtual

Convert the specification of valid values to a readable string.

Caution, a GUI may wish to parse this string so keep the format tight. Typically, type:[valuesdescription], e.g., see derived classes for None:[], List:[A|B|C], etc.

Implemented in jevois::ValidValuesSpecNone< T >, jevois::ValidValuesSpecList< T >, jevois::ValidValuesSpecRange< T >, jevois::ValidValuesSpecStepRange< T >, and jevois::ValidValuesSpecRegex< T >.
