SoSFNode(3)

📦 version 2.5.0, in fedora 43, fedora 44

🌸 NAME 🌸

SoSFNode — bestie, this class is literally just a container for a single node. One node. That's the whole vibe. 💅

(This is the SoSFNode(3) page from the Library Functions Manual, in case you were wondering which manual we're living in.)

✨ SYNOPSIS ✨

#include <Inventor/fields/SoSFNode.h>

It inherits SoSField, so all that parent energy comes along for the ride. 🫶

👑 Detailed Description 👑

Okay so, the SoSFNode class is a container for a single node. That's it. That's the job. 💖

This field container stores a pointer to a Coin node. It also handles all the tedious-but-essential stuff for copy, import and export operations — so you don't have to, bestie, it's got you. ✨

Heads up: the node pointer stored in a field instance of this type may be a NULL pointer. Not a bug, just a fact. 🙈

💅 Member Function Documentation 💅

SoType SoSFNode::getTypeId (void ) const [virtual]

Returns the type identification instance which uniquely identifies the Coin field class the object belongs to. Like a little name tag but for types. 🏷️✨

See also — getClassTypeId(), SoType

Implements SoField.

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

Copy value(s) from f into this field. ⚠️ f must be of the same type as this field — no mixing, no matching, this is not a makeover show. 💀

Implements SoField.

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

Check for equal type and value(s). Both. Not just one. 👯

Implements SoField.

void SoSFNode::fixCopy (SbBool copyconnections) [virtual]

This method is internally called after SoField::copyFrom() during scene graph copies, and it should do the operations necessary for fixing up the field instance after it has gotten a new value. Glow-up maintenance, basically. 🧚

The default method in the SoField superclass does nothing.

The application programmer should normally not need to consider this method — unless he constructs a complex field type which contains new references to container instances (i.e. nodes or engines). Overriding this method is then necessary to update the reference pointers, as they could have been duplicated during the copy operation. 👀

Reimplemented from SoField.

References SoBase::assertAlive(), SoNode::copy(), and SoFieldContainer::findCopy().

SbBool SoSFNode::referencesCopy (void ) const [virtual]

Returns TRUE if this field has references to any containers in the scene graph which are also duplicated during the copy operation. 🌀

Note that this method only is valid to call during copy operations. Timing is everything, bestie.

See also the note about the relevance of the fixCopy() method for application programmers, as it is applicable on this method aswell.

Reimplemented from SoField.

References SoFieldContainer::checkCopy(), SoPath::getHead(), SoBase::isOfType(), and SoField::referencesCopy().

And that's the whole page, bestie! 🎀 This was SoSFNode(3) from Coin, Version 2.5.0 — that's the source and version stamped on the footer, so now you know exactly which era of Coin you're vibing with. Go forth and store exactly one node. Periodt. 💅✨
