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

Reimplemented from SoNodeEngine.

Reimplemented in SoVRMLColorInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, SoVRMLOrientationInterpolator, SoVRMLPositionInterpolator, and SoVRMLScalarInterpolator.

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
    }
    else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
      SoGroup * group = (SoGroup *)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.

Returns the SoFieldData class which holds information about inputs in this engine.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

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

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

This 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.

The set_fraction field gets an input signal that triggers a calculation of the next value_changed eventOut value.
