Detailed DescriptionThe SoVRMLInterpolator class is an internal abstract class​. This class collects the two fields that are common for all interpolator nodes, plus common code that operates on these fields​. Since this is an abstract 'helper' class, it does not represent an actual node from the VRML97 specification, so don't use it as such​. For more information, a detailed discussion of interpolators is available in section 4​.6​.8 of the VRML97 specification: http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8
Member Function Documentation
SoType SoVRMLInterpolator::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​. Usage example: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses​. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode​.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine​.h (for engine classes) and so on​. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups​. Implements SoBase​. Reimplemented in SoVRMLScalarInterpolator, SoVRMLPositionInterpolator, SoVRMLOrientationInterpolator, SoVRMLNormalInterpolator, SoVRMLCoordinateInterpolator, and SoVRMLColorInterpolator​.
const SoFieldData * SoVRMLInterpolator::getFieldData (void) const [protected], [virtual]Returns a pointer to the class-wide field data storage object for this instance​. If no fields are present, returns NULL​. Reimplemented from SoFieldContainer​. Reimplemented in SoVRMLScalarInterpolator, SoVRMLPositionInterpolator, SoVRMLOrientationInterpolator, SoVRMLNormalInterpolator, SoVRMLCoordinateInterpolator, and SoVRMLColorInterpolator​.
const SoEngineOutputData * SoVRMLInterpolator::getOutputData (void) const [virtual]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer​.

Implements SoNodeEngine​. Reimplemented in SoVRMLScalarInterpolator, SoVRMLPositionInterpolator, SoVRMLOrientationInterpolator, SoVRMLNormalInterpolator, SoVRMLCoordinateInterpolator, and SoVRMLColorInterpolator​.
int SoVRMLInterpolator::getKeyValueIndex (float & interp, int numvalues) [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer​.

Member Data Documentation
SoMFFloat SoVRMLInterpolator::keyThis field contains a set of floating point values which the interpolation will run over​. The key values should be monotonically non-decreasing​. The field is inherited from it's declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes​. See the class documentation of the non-abstract VRML interpolator node you want to use for information on what the key values represent in that specific context​.
SoSFFloat SoVRMLInterpolator::set_fractionThe set_fraction field gets an input signal that triggers a calculation of the next value_changed eventOut value​. The field is inherited from it's declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes​.
