Class Method Details

.for(dummy_params = {}, &blk) ⇒ Object

Creates a new subclass of Derailleur::Handler that will create a Derailleur::Context which in turn will evaluate the block. The dummy_params parameter is not used, but we need it because it is the interface for Derailleur.Grease (in case you want to use a custom HandlerGenerator)
