SoInfo(3)

NAME
SoInfo - The SoInfo class is a node for holding text information.

This is simply a placeholder for textual information about a scene. Typically used for specifying author and copyright information in Inventor format files, but can also be used for other purposes, of course.

SYNOPSIS

#include <Inventor/nodes/SoInfo.h>

Inherits SoNode.

Detailed Description

The SoInfo class is a node for holding text information.

This is simply a placeholder for textual information about a scene. Typically used for specifying author and copyright information in Inventor format files, but can also be used for other purposes, of course. SoInfo nodes does not influence traversal in any way for any of the builtin actions.

FILE FORMAT/DEFAULTS:

Info {
    string "<Undefined info>"
}

  SoInfo::SoInfo (void)
Constructor.

  SoInfo::~SoInfo () [protected], [virtual]
Destructor.

Member Function Documentation

  SoType SoInfo::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.

Implements SoBase.

  const SoFieldData * SoInfo::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.
