✨ SoMFFloat ✨

okay so bestie, welcome to SoMFFloat from the Coin library 💖 this is the manual page for it, and yes it's giving container-for-floating-point-values energy, and honestly? iconic.

🌸 NAME 🌸

SoMFFloat — the class that is literally a container for floating point values. that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

#include <Inventor/fields/SoMFFloat.h>

Inherits SoMField. yeah she's got a whole family tree, we love a legacy moment 👑

💫 Detailed Description 💫

okay so the SoMFFloat class is a container for floating point values. literally her whole purpose 🫶

This field is used where nodes, engines or other field containers need to store a group of multiple floating point values. she's the group-project friend who actually holds all the numbers.

This field supports application data sharing through a setValuesPointer() method. See SoMField documentation for information on how to use this function. iykyk 💅

🔥 Member Function Documentation 🔥

void * SoMFFloat::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: bestie this is not for you, it's housekeeping 🧹)

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

SoType SoMFFloat::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoMFFloat::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 SoMFFloat::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, we're not messy 💅

Implements SoField.

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

Check for equal type and value(s).

Implements SoField.

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

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoMField.

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

This method is used for moving values around internally within a multivalue field. It needs to be overridden in each field so it automatically takes care of running copy constructors where necessary.

Implements SoMField.

const float * SoMFFloat::getValues (const int start) const [inline]

Returns a pointer to the values array. that's it that's the function ✨

void SoMFFloat::initClass (void ) [static]

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