NAME

SoResetTransform -

SYNOPSIS

#include <Inventor/nodes/SoResetTransform.h>

Inherits SoTransformation.

Detailed Description

The SoResetTransform class is a node type which makes it possible to 'nullify' state during traversal.

SoResetTransform is useful for setting up geometry in the scene graph which will not be influenced by the transformation nodes before it during traversal.

Member Function Documentation

SoType SoResetTransform::getClassTypeId (void) [static]

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

Reimplemented from SoTransformation.

SoType SoResetTransform::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.

const SoFieldData ** SoResetTransform::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 SoTransformation.

const SoFieldData * SoResetTransform::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 SoTransformation.

void SoResetTransform::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 SoTransformation.
