💖 SoMFVec2d 💖

okay so bestie, welcome to SoMFVec2d(3) — that's the page name, and this whole thing lives in the Library Functions Manual. It's giving "a container for SbVec2d vectors" energy and honestly? iconic. let's get into it 🫶

🦋 Detailed Description 🦋

The SoMFVec2d class is a container for SbVec2d vectors. periodt. 💅

This field is used where nodes, engines or other field containers needs to store an array of vectors with two elements. like, an array of two-element vectors, bestie. that's the whole job. ✨

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

🔥 Member Function Documentation 🔥

SoType SoMFVec2d::getTypeId (void ) const [virtual]

Returns the type identification instance which uniquely identifies the Coin field class the object belongs to. it's the field's little ID card, no cap 🪪

See also

getClassTypeId(), SoType

Implements SoField.

void SoMFVec2d::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, bestie, that's the rule 🙅‍♀️

Implements SoField.

SbBool SoMFVec2d::isSame (const SoField & f) const [virtual]

Check for equal type and value(s). both things. type and values. 👯

Implements SoField.

void SoMFVec2d::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. so like... it's giving "you don't need this, bestie, trust" 🫣

Implements SoMField.

void SoMFVec2d::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 contructors where necessary.

Implements SoMField.

const SbVec2d * SoMFVec2d::getValues (const int start) const [inline]

Returns a pointer to the values array. just... hands you the pointer. here bestie, take it 🫴

References SoMField::num.

void SoMFVec2d::setValues (int start, int numarg, const double xy[][2])

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

References SoMField::maxNum, SoMField::num, and SoField::valueChanged().

void SoMFVec2d::set1Value (int idx, double x, double y)

Set the vector at idx. one vector, two doubles, done ✨

void SoMFVec2d::set1Value (int idx, const double xy[2])

Set the vector at idx. same thing, array edition 🎀

void SoMFVec2d::setValue (double x, double y)

Set this field to contain a single vector with the given element values. single. one. solo. main character vector 💅

void SoMFVec2d::setValue (const double xy[2])

Set this field to contain a single vector with the given element values.

References SoMField::setNum().

okay so that's the whole page bestie!! 💖 this was Coin, Version 2.5.0 — that's the source and version for the SoMFVec2d(3) page, and yeah the footer line is literally just that version stamp, so now you have it. go forth and store your arrays of two-element vectors, you absolute icon 🌈💅🦋
