Additional Inherited Members

Detailed DescriptionThe SoVRMLIndexedLine class is an abstract superclass for lines specified with indices​. This API member is considered internal to the library, as it is not likely to be of interest to the application programmer​.


Member Function Documentation

SoType SoVRMLIndexedLine::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 SoVRMLVertexLine​. Reimplemented in SoVRMLIndexedLineSet​.

const SoFieldData * SoVRMLIndexedLine::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 SoVRMLVertexLine​. Reimplemented in SoVRMLIndexedLineSet​.

void SoVRMLIndexedLine::computeBBox (SoAction * action, SbBox3f & box, SbVec3f & center) [protected], [virtual]Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box​. The bounding box and center point should be calculated and returned in the local coordinate system​. The method implements action behavior for shape nodes for SoGetBoundingBoxAction​. It is invoked from SoShape::getBoundingBox()​. (Subclasses should not override SoNode::getBoundingBox()​.) The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry​. Implements SoShape​.

void SoVRMLIndexedLine::notify (SoNotList * l) [protected], [virtual]Notifies all auditors for this instance when changes are made​. Reimplemented from SoVRMLVertexLine​. References SoVRMLVertexLine::notify()​.
