💖 SoMFVec2f — the Coin manual page, but make it make sense 💖

okay bestie, welcome to the <pink>SoMFVec2f(3)</pink> page from the Coin manual 🎀 this is a whole 3 section vibe, so grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

SoMFVec2f — the class that's literally just a container for SbVec2f vectors. that's it. that's the whole job. 💅

🌸 SYNOPSIS 🌸

#include <Inherits SoMField.h>

wait no hold on 😭 let me not do that. the actual line is:

#include <Inventor/fields/SoMFVec2f.h>

and yeah, it Inherits SoMField. 👑

💫 Detailed Description 💫

SoMFVec2f is a container for SbVec2f vectors. no cap. 📦

so where do you even use this? it's the field you reach for when nodes, engines, or any other field container needs to hold an array of vectors with two elements. two. like x and y. that's the whole shape of it. 🎯

and here's the fun part, bestie: this field supports application data sharing through a setValuesPointer() method. 🫶 if you wanna know how to actually use that function, go read the SoMField documentation — that's where the tea is. 🍵

🔥 Member Function Documentation 🔥

void * SoMFVec2f::createInstance (void ) [static]

okay so this one is considered internal to the library — like, it's not likely to be of interest to the application programmer. 🙈 so if you're just writing app code, you can scroll past, no shade.

what it does: creates a new instance of the class type corresponding to the SoType object. ✨

SoType SoMFVec2f::getClassTypeId (void ) [static]

this static method returns the SoType object that's associated with objects of this class. simple as. 💅

SoType SoMFVec2f::getTypeId (void ) const [virtual]

returns the type identification of an object derived from a class that inherits SoField. this is the one you use for runtime type checking and "downward" casting. iykyk. 🔍

Implements SoField.

void SoMFVec2f::copyFrom (const SoField & f) [virtual]

copies value(s) from f into this field. ⚠️ heads up though: f must be of the same type as this field, or it's not gonna be a good time.

Implements SoField.

SbBool SoMFVec2f::isSame (const SoField & f) const [virtual]

checks for equal type and value(s). both. not one or the other. 💖

Implements SoField.

void SoMFVec2f::deleteAllValues (void ) [protected], [virtual]

another one that's internal to the library and not likely to be of interest to the application programmer. 🫣

Implements SoMField.

void SoMFVec2f::copyValue (int to, int from) [protected], [virtual]

this method is used for moving values around internally within a multivalue field. 🌀 and here's the why: it needs to be overridden in each field so that it automatically takes care of running copy constructors where necessary. it's giving very much "plumbing, but make it correct."

Implements SoMField.

const SbVec2f * SoMFVec2f::getValues (const int start) const [inline]

returns a pointer to the values array. that's the whole thing. pointer. array. go. 👉✨

void SoMFVec2f::initClass (void ) [static]

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

void SoMFVec2f::setValues (int start, int numarg, const float xy[][2])

set num vector array elements from xy, starting at index start. 📝

void SoMFVec2f::set1Value (int idx, float x, float y)

set the vector at idx. 🎯

void SoMFVec2f::set1Value (int idx, const float xy[2])

set the vector at idx. (yes, again — different signature, same energy 💅)

void SoMFVec2f::setValue (float x, float y)

set this field to contain a single vector with the given element values. one vector. that's the vibe. 1️⃣

void SoMFVec2f::setValue (const float xy[2])

set this field to contain a single vector with the given element values. same deal, array-flavored. 🍓
