Detailed Description

template<typename T>
class sensesp::ValueProducer< T >

A base class for any sensor or piece of code that outputs a value for consumption elsewhere.

They are Observable, allowing code to be notified whenever a new value is available. They can be connected directly to ValueConsumers of the same type using the connect_to() method.

inline

Connect a producer to a transform with a different input type.

This allows you to connect a producer to a transform with a different input type. Automatic type conversion is performed.

Template Parameters

VConsumer	ValueConsumer type
CInput	Consumer input type

Parameters

consumer_producer

Transform object to connect to

Returns

std::shared_ptr<VConsumer> The connected consumer
