Detailed Description

The SoWriteAction class writes a scene graph to file.

When applied to a scene, this action writes its contents to the stream contained within an SoOutput instance. This can be a file, a memory buffer or a system filehandle like stdout, for instance.

All information considered part of the scene graph should be written out, including not only nodes, but also the nodes' field values, global fields (at least those with connections inside the scene the action is applied to), engines in the scene, paths, etc.

The scene is written in the Open Inventor file format. Files in this format can be parsed into their scene graph structures by using the SoDB::readAll() method (SoDB also contains a few other import methods you can use).

Constructor & Destructor Documentation

SoWriteAction::SoWriteAction (  void    )

Default constructor. Output will be written to stdout in ASCII format.

SoWriteAction::SoWriteAction (  SoOutput *    out )

Constructor. Output will be written via the out object.

SoWriteAction::~SoWriteAction (  void    )  [virtual]

Destructor.

Member Function Documentation

void SoWriteAction::initClass (  void    )  [static]

Initializes the run-time type system for this class, and sets up the enabled elements and action method list. Reimplemented from SoAction.

SoOutput * SoWriteAction::getOutput (  void    )  const

Returns a pointer to the SoOutput object we're using when writing the scene graph.

void SoWriteAction::continueToApply (  SoNode *    node )

Applies the write method to the subgraph starting at node with the current SoOutput instance, without resetting any of the internal state of the action instance. This should normally be for internal use only.

void SoWriteAction::continueToApply (  SoPath *    path )

Applies the write method to path with the current SoOutput instance, without resetting any of the internal state of the action instance. This should normally be for internal use only.

void SoWriteAction::beginTraversal (  SoNode *    node )  [protected, virtual]

Overloaded from parent class, as the write action is actually done in two passes. The first pass is done to count the references of the objects in the scene graph and otherwise prepare instance in the scene for export. The second pass does the actual writing. Reimplemented from SoAction.

SbBool SoWriteAction::shouldCompactPathLists (  void    )  const [protected, virtual]

For internal use only.
