Member Function Documentation

SoType SoInterpolateVec4f::getClassTypeId void   )  [static]
 

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

Reimplemented from SoInterpolate.

SoType SoInterpolateVec4f::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
    }
    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.

Reimplemented from SoInterpolate.

const SoFieldData ** SoInterpolateVec4f::getInputDataPtr void   )  [static, protected]
 

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

Reimplemented from SoInterpolate.

const SoEngineOutputData ** SoInterpolateVec4f::getOutputDataPtr void   )  [static, protected]
 

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

Reimplemented from SoInterpolate.

const SoFieldData * SoInterpolateVec4f::getFieldData void   )  const [virtual]
 

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

Reimplemented from SoInterpolate.

const SoEngineOutputData * SoInterpolateVec4f::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.

Reimplemented from SoInterpolate.

void SoInterpolateVec4f::initClass void   )  [static]
 

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

Reimplemented from SoInterpolate.
