Detailed Description

The SoGlobalSimplifyAction class is for globally simplifying the geometry of a scene graph, globally.

Constructor & Destructor Documentation

SoGlobalSimplifyAction::SoGlobalSimplifyAction

(

void

)

A constructor.

SoGlobalSimplifyAction::~SoGlobalSimplifyAction ( void  )

virtual

The destructor.

Member Function Documentation

SoType SoGlobalSimplifyAction::getTypeId ( void  ) const

virtual

Returns the type identification of an action derived from a class inheriting SoAction. This is used for run-time type checking and "downward" casting.

Usage example:

void bar(SoAction * action)
{
  if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
    // safe downward cast, know the type
    SoGLRenderAction * glrender = (SoGLRenderAction *)action;
  }
  return; // ignore if not renderaction
}

For application programmers wanting to extend the library with new actions: 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 Inventor/nodes/SoSubAction.h: SO_ACTION_SOURCE, SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

For more information on writing Coin extensions, see the SoAction class documentation.

Returns the actual type id of an object derived from a class inheriting SoAction. Needs to be overridden in all subclasses.

Reimplemented from SoSimplifyAction.

void SoGlobalSimplifyAction::addMethod ( const SoType  type, SoActionMethod  method  )

static

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

void SoGlobalSimplifyAction::enableElement ( const SoType  type, const int  stackindex  )

static

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

const SoEnabledElementsList & SoGlobalSimplifyAction::getEnabledElements ( void  ) const

protectedvirtual

Returns a list of the elements used by action instances of this class upon traversal operations.

Reimplemented from SoSimplifyAction.

void SoGlobalSimplifyAction::beginTraversal ( SoNode *  node )

protectedvirtual

This virtual method is called from SoAction::apply(), and is the entry point for the actual scenegraph traversal.

It can be overridden to initialize the action at traversal start, for specific initializations in the action subclasses inheriting SoAction.

Default method just calls traverse(), which any overridden implementation of the method must do too (or call SoAction::beginTraversal()) to trigger the scenegraph traversal.

Reimplemented from SoSimplifyAction.
