Detailed Description

template<typename FilterType, typename... TagsToFilter>
class dg::Actions::Filter< FilterType, tmpl::list< TagsToFilter... > >

Applies a filter to the specified tags.

If different Filters are desired for different tags then multiple Filter actions must be inserted into the action list with different FilterType. Here is an example of an action list with two different exponential filters:

typename Metavariables::Phase, Metavariables::Phase::Testing,
tmpl::list<Tags::VectorVar<dim>, Tags::ScalarVar>>>>>>;
A cached exponential filter.
