SoInfo(3)

✨ NAME ✨

okay so bestie, this is SoInfo(3) from the Coin manual 💖 and we're gonna get through it together, no stress.

SoInfo — a node for holding text information. That's literally the whole personality. She holds text. She does not move, she does not render, she just is. 👑

🦋 SYNOPSIS 🦋

#include <Inventor/nodes/SoInfo.h>

Inherits SoNode. Yes she's a node, she's in the family tree, we love a legacy. 🌈

💅 Public Member Functions

• virtual SoType getTypeId (void) const — the virtual type-id getter, standard node fare 🫶
• SoInfo (void) — the constructor, come thru ✨

🧚 Public Member Functions inherited from SoBase

the og base class energy, and yes there's one with an actual explanation so pay attention:

void ref (void) const
void unref (void) const
void unrefNoDelete (void) const
int32_t getRefCount (void) const
void touch (void)
SbBool isOfType (SoType type) const
virtual SbName getName (void) const
virtual void setName (const SbName &newname)
void addAuditor (void *const auditor, const SoNotRec::Type type)
void removeAuditor (void *const auditor, const SoNotRec::Type type)
const SoAuditorList & getAuditors (void) const
SbBool shouldWrite (void)
void assertAlive (void) const

and the lore drop on that one: isOfType returns TRUE if the type of this object is either the same type as type, or inherited from type. iykyk 🫶

🎀 DETAILED DESCRIPTION 🎀

SoInfo is a node for holding text information. periodt.

Basically she's a placeholder — a lil spot for textual information about a scene. The classic use case is putting author and copyright info inside Inventor format files, but honestly she can be used for other purposes too, of course. versatile queen 💅

real talk: SoInfo nodes do not influence traversal in any way for any of the built-in actions. she minds her business, she doesn't touch the pipeline, she simply exists. iconic behaviour honestly ✨

🌈 FILE FORMAT/DEFAULTS

Info {
    string "<Undefined info>"
}

💖 CONSTRUCTOR & DESTRUCTOR DOCUMENTATION 💖

🦋 SoInfo::SoInfo (void )

Constructor. she's born 🫶

🧚 SoInfo::~SoInfo () [protected], [virtual]

Destructor. she's gone 😭 (it's protected and virtual, so mind your manners)

✨ MEMBER FUNCTION DOCUMENTATION ✨

okay bestie, this is the part where we meet the actual functions, and honestly? they're giving "quiet overachiever" energy. let's go one by one 💅

---

🦋 SoType SoInfo::getClassTypeId(void) — [static]

this one's a static method, meaning you don't need an actual instance of anything to call it — it just sits there, ready, like a bestie who always picks up the phone.

it returns the SoType object that's associated with objects of this class. that's it, that's the whole vibe. 🫶

---

🦋 SoType SoInfo::getTypeId(void) const — [virtual]

this cutie returns the type identification of an object derived from a class that inherits SoBase.

what's it for? two things, and they're both lowkey iconic:

• runtime type checking — figuring out what something actually is while the program's running
• "downward" casting — which, yes, is literally in quotes in the original, so we're keeping the quotes. dramatic. we love a quoted "downward".

this one implements SoBase, so it's carrying that legacy, no cap.

---

🦋 const SoFieldData ** SoInfo::getFieldDataPtr(void) — [static], [protected]

🙈 heads up bestie: this API member is considered internal to the library, because it is not likely to be of interest to the application programmer. so if you're just out here building apps, this one's not your girl. it's giving backstage pass, iykyk.

it returns the SoFieldData class, which holds all the info about the fields in this node. very much the "files the paperwork" of the family. 💀

---

🦋 const SoFieldData * SoInfo::getFieldData(void) const — [protected], [virtual]

this one hands you a pointer to the class-wide field data storage object for this particular instance.

and here's the one technical caveat you cannot skip: if there are no fields present, it returns NULL. so check before you dereference, bestie, please, for me. 😭

also — it's reimplemented from SoFieldContainer. passing the torch, iconic behavior. ✨

🌸 MEMBER DATA DOCUMENTATION 🌸

🍓 SoSFString SoInfo::string

that's the data member, right there, in all its glory.

its job? text information. short description, huge responsibility. a legend. 👑

and that's a wrap on SoInfo(3), bestie!! this whole page came to you from version 4.0.10, dated Thu Jun 25 2026 00:00:00 — go forth, call these functions responsibly, and remember: NULL checks are self care. 🎀💖✨
