Member Function Documentation

template<class T> virtual T YAnyOpt< T >::defaultValue (   )  const [protected, pure virtual]

The default value - the value that will be returned if none has been explicitly set. Overwrite this method with the class specific default value. Implemented in YBoolOpt, and YLongOpt.

template<class T> bool YAnyOpt< T >::defined (   )  const [inline]

Return whether or not the value is defined, i.e. whether or not a value has been set before.

template<class T> void YAnyOpt< T >::setValue (  T  newValue  )  [inline]

Set the value.

template<class T> void YAnyOpt< T >::undef (   )  [inline]

Invalidate the value, i.e. make it undefined - just like at object creation time.

template<class T> T YAnyOpt< T >::value (   )  const [inline]

Returns the value of this option, if any has been defined, or the default value otherwise.
