#include <jevois/Component/Parameter.H>

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

Dynamic parameter added to a component at runtime.

Dynamic parameters can only be accessed by descriptor at the Component level (using getParamVal(), setParamVal(), etc), since there is no unique class type for them and the owning Component does not inherit from them. Typically for use via Component::addDynamicParameter(). Use with caution. Mainly developed to enable endowing python modules with JeVois parameters.
