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 scenegraph 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 "<Undefined file>"
    }

Member Function Documentation

void SoFile::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 SoNode.

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 who wants to throw geometry primitives at OpenGL overrides 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 calculates their bounding box also overrides 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 overrides 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 calculates their primitive count also overrides 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.

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.

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 / persistant 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
