✨ SoFieldSensor ✨

okay bestie, we're in the Coin section 3 manual pages and today's main character is SoFieldSensor 💅

🌸 NAME 🌸

SoFieldSensor — the class that detects changes to a field. she's nosy, she's observant, she's literally doing surveillance (affectionate) 🦋

👑 Detailed Description 👑

The SoFieldSensor class detects changes to a field. periodt 💅

Attach a field to a sensor of this type to put it under surveillance, so you can act upon changes to the field. she's watching. always watching. it's giving bodyguard energy. 👀

An SoFieldSensor can also act for delete-callback purposes alone and does not need a regular notification-based callback. so like, she can show up just to handle the goodbye, no RSVP required 🫶

🧚 Constructor & Destructor Documentation 🧚

💖 SoFieldSensor::SoFieldSensor (void )

Constructor. the classic no-args entrance. iconic. ✨

💖 SoFieldSensor::SoFieldSensor (SoSensorCB * func, void * data)

Constructor taking as parameters the sensor callback function and the userdata which will be passed to the callback.

• setFunction(), setData()

💖 SoFieldSensor::~SoFieldSensor (void ) [virtual]

Destructor. she's leaving the group chat 😭

🌈 Member Function Documentation 🌈

🌸 void SoFieldSensor::attach (SoField * field)

Attach sensor to a field. Whenever the field's value changes, the sensor will be triggered and call the callback function. it's giving "notify me when he posts" 🔔

A field sensor can be attached to only a single field at a time. When this method is invoked multiple times, each subsequent call will replace the field the sensor is monitoring with the new field. monogamous sensor behavior, no cap. 💀

When the given field is deleted, the sensor will automatically be detached. she knows when to let go 🦋

See also

• detach()

🌸 void SoFieldSensor::detach (void )

Detach sensor from field. As long as an SoFieldSensor is detached, it will never call its callback function. she's on do-not-disturb, fr fr. 🔇

See also

• attach()

🌸 SoField * SoFieldSensor::getAttachedField (void ) const

Returns a pointer to the field connected to the sensor. so you can find out who she's currently keeping tabs on. 👑

See also

• attach(), detach()

🌸 void SoFieldSensor::trigger (void ) [virtual]

Trigger the sensor's callback function. the moment we've all been waiting for. the callback. she ate. 🔥

Reimplemented from SoDataSensor.
