Detailed Description

A static registry used to register and build values of different types for the WebServerControl.

Needed due to the complexities of parsing parameter types from generic JSON received by the web server.

add()

template<class ControlledValue , class ValueType >

char Moose::WebServerControlTypeRegistry::add ( const std::string &  type_name, std::function< ValueType(const nlohmann::json &)> &&  parse_function  )

static

Register a type in the registry.

Template Parameters

ControlledValue	The derived ControlledValueBase class that contains the implementation for setting the controllable value
ValueType	The underlying type of the value to be controlled

Parameters

type_name	Human readable name for the type of the value to be controlled
parse_function	Function used to parse the value from JSON
