SoVRMLIndexedLine(3)

NAME
SoVRMLIndexedLine - The 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.

Detailed Description

The 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
  }
}

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.

  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.

Reimplemented in SoVRMLIndexedLineSet.
