SoMFDouble(3)

okay bestie, welcome to SoMFDouble(3) — it's a Coin manual page, it's giving ✨container energy✨, and by the end of this you're gonna be fluent, no cap. 💅

---

✨ NAME ✨

SoMFDouble — the class that is literally a container for double float precision point values. 🫶 That's it. That's the whole vibe.

---

🌸 SYNOPSIS 🌸

First things first, you gotta include the header, or nothing happens, fr fr:

#include <Inventor/fields/SoMFDouble.h>

And it inherits from SoMField. Iconic lineage, honestly. 👑

💅 Detailed Description 💅

So the whole tea is: the SoMFDouble class is a container for double float precision point values. 🫶

Where's it used tho? This field shows up wherever nodes, engines or other field containers need to store a group of multiple floating point values. Like, a whole lil squad of doubles. It's giving group chat. 😭

And bestie, it supports application data sharing through a setValuesPointer() method. Go check the SoMField documentation for the deets on how to use that function — I'm not gatekeeping, it's literally right there. ✨

🧚 Member Function Documentation 🧚

🌟 void * SoMFDouble::createInstance (void ) [static]

Okay so this one is internal to the library — it is not likely to be of interest to the application programmer, so don't stress about it. 🙈

What it does: creates a new instance of the class type corresponding to the SoType object. That's the whole job. 💅

🌟 SoType SoMFDouble::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. Easy. Iconic. No notes. ✨

🌟 SoType SoMFDouble::getTypeId (void ) const [virtual]

This one returns the type identification of an object derived from a class inheriting SoField. It's used for runtime type checking and "downward" casting. 👑

And Implements SoField. Periodt. 💖

🌟 void SoMFDouble::copyFrom (const SoField & f) [virtual]

Copies the value(s) from f into this field. Heads up tho: f must be of the same type as this field — no mixing, bestie, that's a whole vibe violation. 💀

Implements SoField.

🌟 SbBool SoMFDouble::isSame (const SoField & f) const [virtual]

Checks for equal type and value(s). Basically the vibe check of this class. ✅

Implements SoField.

🌟 void SoMFDouble::deleteAllValues (void ) [protected], [virtual]

Another internal to the library one — not likely to be of interest to the application programmer, so you can lowkey ignore it. 🙈

Implements SoMField.

🌟 void SoMFDouble::copyValue (int to, int from) [protected], [virtual]

This method is used for moving values around internally within a multivalue field. And here's the thing: it needs to be overridden in each field so it automatically takes care of running copy constructors where necessary. Can't skip it, it's mandatory, fr fr. 💅

Implements SoMField.

🌟 const double * SoMFDouble::getValues (const int start) const [inline]

Returns a pointer to the values array. 🫶 That's it, she's simple, she's inline, she slays. ✨

🌟 void SoMFDouble::initClass (void ) [static]

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system. Behind the scenes main character energy. 👑

And that's the whole page, bestie!! 🫶 This was SoMFDouble(3) from the Coin manual, Version 4.0.10, dated Thu Jun 25 2026 00:00:00. Go forth and store your group of multiple floating point values. You got this. Slay. 💖🌸🦋⭐👑
