Member Function Documentation

SoType SoComposeRotationFromTo::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​. Implements SoBase​.

---

const SoFieldData * SoComposeRotationFromTo::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 SoFieldContainer​.

---

const SoEngineOutputData * SoComposeRotationFromTo::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 SoEngine​.
