Detailed Description

template<typename Action>
struct morph::model::ActionKeyTraits< Action >

Declares where an action's model key comes from.

The primary template is the keyless case, which is the default and the common one: such an action says nothing about identity and runs against whichever instance its handler is already attached to. Specialise via BRIDGE_KEY_FROM or BRIDGE_KEY_FROM_RESULT rather than by hand.

Template Parameters

Action

Concrete action type.
