Function Documentation

AddListener()

void EdgeEvent::AddListener	(	EdgeEventListener *	observer,
		bool	priority = false )

Register an EdgeEventListener instance.

Parameters

observer	Listener object pointer.
priority	If true, the listener may be inserted with higher priority (implementation-defined ordering).

Warning

The observer must remain valid until removed via RemoveListener().

AddListenerOnChange()

void EdgeEvent::AddListenerOnChange

(

void(*

onChange )(std::vector< IrSensor > sensors)

)

Register a function callback for sensor state changes.

Parameters

onChange

Function pointer invoked on changes.

Warning

The callback is typically invoked from an internal worker/event thread.

Examples

EdgeControl/main.cpp.

AddListenerOnGapDetect()

void EdgeEvent::AddListenerOnGapDetect

(

void(*

onChange )(GapDirection gap_type)

)

Register a function callback for gap detection events.

Parameters

onChange

Function pointer invoked with the detected gap direction.

Warning

The callback is typically invoked from an internal worker/event thread.

RemoveListener()

void EdgeEvent::RemoveListener

(

EdgeEventListener *

observer

)

Unregister an EdgeEventListener instance.

Parameters

observer

Listener object pointer previously registered.

RemoveListenerOnChange()

void EdgeEvent::RemoveListenerOnChange

(

void(*

onChange )(std::vector< IrSensor > sensors)

)

Unregister a function callback for sensor state changes.

Parameters

onChange

Function pointer previously registered.

Examples

EdgeControl/main.cpp.

RemoveListenerOnGapDetect()

void EdgeEvent::RemoveListenerOnGapDetect

(

void(*

onChange )(GapDirection gap_type)

)

Unregister a function callback for gap detection events.

Parameters

onChange

Function pointer previously registered.
