Detailed Description

template<typename T, typename Tfrom>
class rpcbasic_register_get< T, Tfrom >

Registers a 'get' function to get a parameter over ControlPort.

This class allows us to remotely get a value or parameter of the block over ControlPort. The get occurs by calling a getter accessor function of the class, usually [variable](), which is passed in as function.

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.

Constructor & Destructor Documentation

template<typename T, typename Tfrom>
rpcbasic_register_get< T, Tfrom >::rpcbasic_register_get ( const std::string &  block_alias,
const char *  functionbase,
Tfrom(T::*)()  function,
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.

This constructor is specifically for gr::block's to use to add gettable variables to ControlPort. Generally meant to be used in gr::block::setup_rpc.

Uses the block's alias to create the ControlPort interface. This alias is cross-referenced by the global_block_registry (static variable of type gr::block_registry) to get the pointer to the block.

Parameters
block_aliasBlock's alias; use alias() to get it from the block.
functionbaseThe name of the function that we'll access over ControlPort
functionA function pointer to the real function accessed when called something like: &[block class]::[variable]()
minExpected minimum value the parameter can hold
maxExpected maximum value the parameter can hold
defExpected 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
template<typename T, typename Tfrom>
rpcbasic_register_get< T, Tfrom >::rpcbasic_register_get ( const std::string &  block_alias,
const char *  functionbase,
Tfrom(T::*)() const  function,
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

Same as rpcbasic_register_get::rpcbasic_register_get that allows using '[variable]() const' getter functions.

template<typename T, typename Tfrom>
rpcbasic_register_get< T, Tfrom >::rpcbasic_register_get ( const std::string &  name,
const char *  functionbase,
T *  obj,
Tfrom(T::*)()  function,
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.

Allows us to add non gr::block related objects to ControlPort. Instead of using the block's alias, we give it a name and the actual pointer to the object as obj. We just need to make sure that the pointer to this object is always valid.

Parameters
nameName of the object being set up for ControlPort access
functionbaseThe name of the function that we'll access over ControlPort
objA pointer to the object itself
functionA function pointer to the real function accessed when called something like: &[block class]::set_[variable]()
minExpected minimum value the parameter can hold
maxExpected maximum value the parameter can hold
defExpected 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
template<typename T, typename Tfrom>
rpcbasic_register_get< T, Tfrom >::rpcbasic_register_get ( const std::string &  name,
const char *  functionbase,
T *  obj,
Tfrom(T::*)() const  function,
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

Same as above that allows using '[variable]() const' getter functions.
