Detailed Description

The SoMFVec2f class is a container for SbVec2f vectors. This field is used where nodes, engines or other field containers need to store an array of vectors with two elements.

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

Member Function Documentation

  void * SoMFVec2f::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.
 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 associated with objects of this class.

  SoType SoMFVec2f::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 SoMFVec2f::copyFrom (const SoField & f) [virtual]
Copy value(s) from f into this field. f must be of the same type as this field.

Implements SoField.

  SbBool SoMFVec2f::isSame (const SoField & f) const [virtual]
Check for equal type and value(s).

Implements SoField.

  void SoMFVec2f::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 SoMFVec2f::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 SbVec2f * SoMFVec2f::getValues (const int start) const [inline]
Returns a pointer to the values array.

  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.

  void SoMFVec2f::setValue (float x, float y)
Set this field to contain a single vector with the given element values.

  void SoMFVec2f::setValue (const float xy[2])
Set this field to contain a single vector with the given element values.
