Detailed Description

template<typename T>
class eduart::sensorring::device::Group< T >

Typed wrapper over a vector of device pointers.

Provides iteration (range-for yields T&) and a subscribe() method that subscribes to all devices in the group at once. Returned Subscription manages all individual subscriptions and cancels them collectively.

Template Parameters

T	Device interface type (DepthSensor, ThermalSensor, Light, …).

Member Function Documentation

subscribe()

template<typename T>

template<typename U = T, typename = typename U::MeasurementType>

subscription::Subscription eduart::sensorring::device::Group< T >::subscribe ( std::function< void(const typename U::MeasurementType &)> callback )

inline

Subscribe to all devices in the group.

Returns a single Subscription that manages all individual subscriptions. When cancelled or destroyed, all subscriptions are cancelled.

Only available when T defines a MeasurementType alias (e.g. DepthSensor, ThermalSensor).

Parameters

[in]

callback

Invoked for each measurement from each device.

Returns

RAII Subscription managing all individual subscriptions.

subscribeAll()

template<typename T>

template<typename U = T, typename = typename U::MeasurementType>

subscription::Subscription eduart::sensorring::device::Group< T >::subscribeAll ( std::function< void(const std::vector< typename U::MeasurementType > &)> callback )

inline

Subscribe to all devices in the group with synchronized frame delivery.

The callback is invoked once per complete frame — i.e. only after every device in the group has produced a new measurement. The callback receives a vector containing exactly one measurement per device (ordered by device index). The effective callback rate equals the rate of the slowest device in the group.

Only available when T defines a MeasurementType alias (e.g. DepthSensor, ThermalSensor).

Parameters

[in]

callback

Invoked with a complete frame (one measurement per device, ordered by index).

Returns

RAII Subscription managing all individual subscriptions.
