Member Function Documentation

SoType SoForeignFileKit::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
  }
}

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 * SoForeignFileKit::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.

const SoNodekitCatalog * SoForeignFileKit::getNodekitCatalog (void) const [virtual]

Returns the nodekit catalog which defines the layout of this class' kit.

SbBool SoForeignFileKit::isFileSupported (SoInput * in, SbBool exhaust = FALSE) [static]

Convenience method. Will extract the filename from in and call the other ieFileSupported() method.

Will return false if file is not supported or /e in is not representing a normal file.

SbBool SoForeignFileKit::isFileSupported (const char * filename, SbBool exhaust = FALSE) [static]

Checks if the filename can be read by a registered SoForeignFileKit handler.

FIXME: exhaust is not implemented.

SoForeignFileKit * SoForeignFileKit::createForeignFileKit (SoInput * in, SbBool exhaust = FALSE) [static]

Convenience method. Will extract the filename from in and call the other ieFileSupported() method.

SoForeignFileKit * SoForeignFileKit::createForeignFileKit (const char * filename, SbBool exhaust = FALSE) [static]

Creates an instance of a suitable SoForeignFileKit subtype from the given file and reads its content. Returns NULL on failure or a kit with refcount of 0 on success.

FIXME: exhaust is not implemented.

SbBool SoForeignFileKit::canReadFile (const char * filename = NULL) const [virtual]

Checks if this concrete class can read the given file.

Reimplemented in SoSTLFileKit.

SbBool SoForeignFileKit::readFile (const char * filename) [virtual]

Reads the given file into the internal representation. If successful, Coin should now be able to render the scene. If you need a pure Coin scenegraph, call convert().

Reimplemented in SoSTLFileKit.

SbBool SoForeignFileKit::canWriteFile (const char * filename = NULL) const [virtual]

Checks if this concrete class can write to the given file.

Reimplemented in SoSTLFileKit.

SbBool SoForeignFileKit::writeFile (const char * filename) [virtual]

Writes the current contents to the given file.

canWriteFile

Reimplemented in SoSTLFileKit.

virtual class SoSeparator* SoForeignFileKit::convert () [pure virtual]

Converts (if necessary) the internal representation of the foreign file to a pure Coin scenegraph. Returns the root node with a refcount of 0.

Implemented in SoSTLFileKit.

SbBool SoForeignFileKit::registerFileExtension (SoType handler, SbName extension, SoForeignFileIdentifyFunc * identify) [static], [protected]

Registers a concrete SoForeignFileKit subtype to be a handler for files with the given extension. One class can be a handler for multiple filename extensions.

FIXME: identify is not implemented
