Interface MethodResolver

  • All Known Implementing Classes:
    DataBindingMethodResolver, ReflectiveMethodResolver


    public interface MethodResolver
    A method resolver attempts locate a method and returns a command executor that can be used to invoke that method. The command executor will be cached but if it 'goes stale' the resolvers will be called again.
