## Detailed Description

template<typename Tfrom>
class rpcbasic_register_variable_rw< Tfrom >

Registers a read/write function to get and set a parameter over ControlPort.

This class allows us to remotely get and/or set a value or parameter of the block over ControlPort. Unlike the rpcbasic_register_get class, this version is passed the variable directly and establishes a getter for us, so there is no need to have a getter function already in the object.

This version establishes both get and set functions and so provides read/write access to the variable.

We can set the (expected) minimum (`min`), maximum (`max`), and default (`def`) of the variables we will get. These values are not enforced, however, but can be useful for setting up graphs and other ways of bounding the data.

This class also allows us to provide information to the user about the variable, such as an appropriate unit (`units_`) as well as a description (`desc_`) about what the variable does.

The privilege (`minpriv_`) level is the minimum privilege level a remote must identify with to be able to call this function.

We also provide display hints (`display_`), which can be used by the ControlPort client application to know how to best display or even print the data. This is a mask of options for variables set in rpccallbackregister_base.h. The mask is defined by one of the "DisplayType Plotting Types" and or'd with any of the "DisplayType Options" features. See "Display Options" in ControlPort for details.

inline

Adds the ability to set and get the variable over ControlPort.

Creates new getter and setter accessor functions to read and write `variable`.

Parameters

  namebase | Name of the object being set up for ControlPort access
  functionbase | The name of the function that we'll access over ControlPort
  variable | A pointer to the variable, possibly as a member of a class
  min | Expected minimum value the parameter can hold
  max | Expected maximum value the parameter can hold
  def | Expected default value the parameter can hold
  units_ | A string to describe what units to represent the variable with
  desc_ | A string to describing the variable.
  minpriv | The required minimum privilege level
  display_ | The display mask
