Detailed Description

template<typename Tfrom>
class rpcbasic_register_variable< Tfrom >

Registers a read-only function to get a parameter over ControlPort.

This class allows us to remotely get 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 is for read-only get access.

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.

template<typename Tfrom >

rpcbasic_register_variable< Tfrom >::rpcbasic_register_variable ( )

Empty constructor which should never be called but needs to exist for ues in varous STL data structures

rpcbasic_register_variable() [2/2]

template<typename Tfrom >

rpcbasic_register_variable< Tfrom >::rpcbasic_register_variable ( const std::string &  namebase, const char *  functionbase, Tfrom *  variable, const pmt::pmt_t &  min, const pmt::pmt_t &  max, const pmt::pmt_t &  def, const char *  units_ = "", const char *  desc_ = "", priv_lvl_t  minpriv_ = RPC_PRIVLVL_MIN, DisplayType  display_ = DISPNULL  )

inline

Adds the ability to get the variable over ControlPort.

Creates a new getter accessor function to read 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
