okay bestie, sit down, hydrate, and let's talk about SoSFNode(3) — the Coin manual page you're gonna actually enjoy reading. no cap. 🫶

🌸 NAME 🌸

SoSFNode — the class that is literally a container for a single node. one node. that's it. that's the assignment. 💅

✨ SYNOPSIS ✨

#include <Inventor/fields/SoSFNode.h>

Inherits SoSField. yes queen, it's part of the field family tree 🌳

💜 Detailed Description 💜

The SoSFNode class is a container for a single node. say it with me: single. node. 🎀

This field container stores a pointer to a Coin node. It takes care of the necessary functionality for handling copy, import and export operations. it's the responsible friend who handles the logistics so you don't have to. 🫶

heads up bestie: note that the node pointer stored in a field instance of this type may be a NULL pointer. so like… it can be empty. that's allowed. it's giving "single and ready to mingle" but the mingle is optional. 💀

📖 Member Function Documentation 📖

🫧 void * SoSFNode::createInstance (void ) [static]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. translation: not your business, girlie, the library handles it. 🙈

Creates a new instance of the class type corresponding to the SoType object.

🫧 SoType SoSFNode::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. it's the class's little ID card ✨

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

Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and "downward" casting.

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 types, that's the rule ✋

Implements SoField.

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

Check for equal type and value(s). a vibe check, essentially 💅

Implements SoField.

🫧 void SoSFNode::initClass (void ) [static]

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.

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

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

The default method in the SoField superclass does nothing. iconic behaviour honestly, doing nothing is a valid lifestyle 💀

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.

🫧 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.

careful bestie: note that this method only is valid to call during copy operations. timing is everything, periodt.

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

Reimplemented from SoField.
