static SbUniqueId nextUniqueId = 1 static int nextActionMethodIndex = 0 Detailed Description The SoFile class is node container for another model file. This node provides a way to split your models into a set of 'component' models to include into larger 'master' files. Just provide the name of the model file to include in the SoFile::name field, and it will automatically be loaded and have its nodes inserted into the scene graph at the point of the SoFile node. You can also set the SoFile::name field manually. Such an action will then automatically trigger an invocation of a read operation which imports the filename you set in the field. FILE FORMAT/DEFAULTS: File { name "" } Constructor & Destructor Documentation SoFile::SoFile (void ) Constructor. SoFile::~SoFile () [protected], [virtual] Destructor. Member Function Documentation SoType SoFile::getClassTypeId (void ) [static] This static method returns the SoType object associated with objects of this class. SoType SoFile::getTypeId (void ) const [virtual] Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting. Implements SoBase. const SoFieldData ** SoFile::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. Returns the SoFieldData class which holds information about fields in this node. const SoFieldData * SoFile::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 SoFile::doAction (SoAction * action) [virtual] This function performs the typical operation of a node for any action. Reimplemented from SoNode. void SoFile::callback (SoCallbackAction * action) [virtual] Action method for SoCallbackAction. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. Reimplemented from SoNode. void SoFile::GLRender (SoGLRenderAction * action) [virtual] Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Reimplemented from SoNode. void SoFile::getBoundingBox (SoGetBoundingBoxAction * action) [virtual] Action method for the SoGetBoundingBoxAction. Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node. Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables. Reimplemented from SoNode. void SoFile::getMatrix (SoGetMatrixAction * action) [virtual] Action method for SoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented from SoNode. void SoFile::handleEvent (SoHandleEventAction * action) [virtual] Action method for SoHandleEventAction. Inspects the event data from action, and processes it if it is something which this node should react to. Nodes influencing relevant state variables for how event handling is done also override this method. Reimplemented from SoNode. void SoFile::pick (SoPickAction * action) [virtual] Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoNode. void SoFile::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual] Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables. Reimplemented from SoNode. void SoFile::audioRender (SoAudioRenderAction * action) [virtual] Action method for SoAudioRenderAction. Does common processing for SoAudioRenderAction action instances. Reimplemented from SoNode. void SoFile::search (SoSearchAction * action) [virtual] Action method for SoSearchAction. Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node. See also SoSearchAction Reimplemented from SoNode. SoGroup * SoFile::copyChildren (void ) const Returns a subgraph with a deep copy of the children of this node. SoChildList * SoFile::getChildren (void ) const [virtual] Returns list of children for this node. Reimplemented from SoNode. void SoFile::copyContents (const SoFieldContainer * from, SbBool copyconnections) [virtual] Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE. This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically. For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function: SoNode * mynewnode = templatenode->copy(); The same also goes for engines. Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this: void MyCoinExtensionNode::copyContents(const SoFieldContainer * from, SbBool copyconnections) { // let parent superclasses do their thing (copy fields, copy // instance name, etc.) SoNode::copyContents(from, copyconnections); // [..then copy internal data..] } Reimplemented from SoNode. const SbString & SoFile::getFullName (void ) const Returns the read filename, possibly including the (relative) path where the file was found. Returns an empty string if no file has been read. This method is an extension versus the Open Inventor API. void SoFile::setSearchOK (SbBool dosearch) [static] Enables/disables searching children using SoSearchAction. SbBool SoFile::getSearchOK () [static] Returns whether searching children using SoSearchAction is enabled. SbBool SoFile::readInstance (SoInput * in, unsigned short flags) [protected], [virtual] This method is mainly intended for internal use during file import operations. It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type. TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE. flags is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from SoNode. SbBool SoFile::readNamedFile (SoInput * in) [protected], [virtual] Read the file named in the SoFile::name field. Used to be a private method, moved into protected space to enable subclasses to detect when the file is (re)read. Since Coin 2.0 Member Data Documentation SoSFString SoFile::name Filename for model file to insert in the scene graph at the location of the SoFile node.
