NAME

SoVRMLWorldInfo -

SYNOPSIS



#include <Inventor/VRMLnodes/SoVRMLWorldInfo.h>

Inherits SoNode.

Detailed Description

The SoVRMLWorldInfo class contains information about the VRML scene.

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:. 

  WorldInfo {
    field MFString info  []
    field SFString title ""
  }
  .fi


The WorldInfo node contains information about the world. This node is strictly for documentation purposes and has no effect on the visual appearance or behaviour of the world. The title field is intended to store the name or title of the world so that browsers can present this to the user (perhaps in the window border). Any other information about the world can be stored in the info field, such as author information, copyright, and usage instructions.

Member Function Documentation

SoType SoVRMLWorldInfo::getClassTypeId (void) [static]

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

Reimplemented from SoNode.

SoType SoVRMLWorldInfo::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 ** SoVRMLWorldInfo::getFieldDataPtr (void) [static, protected]

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

Reimplemented from SoNode.

const SoFieldData * SoVRMLWorldInfo::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 SoFieldContainer.

void SoVRMLWorldInfo::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 SoNode.

Member Data Documentation

SoSFString SoVRMLWorldInfo::title

World title strings.

SoMFString SoVRMLWorldInfo::info

Info strings.
