SimpleClosure< SIG > Class Template Reference

#include "steam/control/command-simple-closure.hpp"

Description

template<typename SIG>
class steam::control::SimpleClosure< SIG >

Dummy / proof-of-concept implementation of CmdClosure.

It is a specifically typed subclass, which serves to hold storage for the concrete invocation arguments within an inline buffer.

Note

for demonstration and unit testing

SimpleClosure()

SimpleClosure ( )

inline

per default, all data within StorageHolder is set up in empty state.

Later on, the command arguments are to be provided by #bind , whereas the undo functions will be wired by #tie

assign a new set of parameter values to this.

Note

the values are passed packaged into a sequence of GenNode elements. This is the usual way arguments are passed from the UI-Bus
