NAME

       SoMFVec2d -

       The SoMFVec2d class is a container for SbVec2d vectors.

       This field is used where nodes, engines or other field containers needs
       to store an array of vectors with two elements.

Detailed Description

       The SoMFVec2d class is a container for SbVec2d vectors.

       This field is used where nodes, engines or other field containers needs
       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.

           Coin, and it is not available in the original SGI Open Inventor
           v2.1 API.

       Since:
           Coin 2.5

Member Function Documentation

   static SoType SoMFVec2d::getClassTypeId (void) [static] Returns a unique
       type identifier for this field class.
       See also:
           getTypeId(), SoType

       Reimplemented from SoMField.

   virtual SoType SoMFVec2d::getTypeId (void) const [virtual] Returns the type
       identification instance which uniquely identifies the Coin field class
       the object belongs to.
       See also:
           getClassTypeId(), SoType

       Implements SoField.

   virtual 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.
       Implements SoField.

   virtual SbBool SoMFVec2d::isSame (const SoField & f) const [virtual] Check
       for equal type and value(s).
       Implements SoField.

   const SbVec2d* SoMFVec2d::getValues (const int start) const [inline]
        Returns a pointer to the values array. .SS "void SoMFVec2d::initClass
       (void) [static]"Internal method called upon initialization of the
       library (from SoDB::init()) to set up the type system.
       Reimplemented from SoMField.

   void SoMFVec2d::setValues (int start, int numarg, const double xy[][2]) Set
       num vector array elements from xy, starting at index start.
   void SoMFVec2d::set1Value (int idx, double x, double y) Set the vector at
       idx.
   void SoMFVec2d::set1Value (int idx, const double xy[2]) Set the vector at
       idx.
   void SoMFVec2d::setValue (double x, double y) Set this field to contain a
       single vector with the given element values.
   void SoMFVec2d::setValue (const double xy[2]) Set this field to contain a
       single vector with the given element values.
