Coin 3.0

Member Function Documentation

◆ getTypeId()

SoType SoForeignFileKit::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.

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 predefined 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 top level superclasses for the various class groups.

Reimplemented from SoBaseKit.

Reimplemented in SoSTLFileKit.

◆ getFieldData()

const SoFieldData * SoForeignFileKit::getFieldData ( void  ) const
protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoBaseKit.

Reimplemented in SoSTLFileKit.

◆ getNodekitCatalog()

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

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

Reimplemented from SoBaseKit.

Reimplemented in SoSTLFileKit.

◆ isFileSupported() [1/2]

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.

◆ isFileSupported() [2/2]

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.

◆ createForeignFileKit() [1/2]

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

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

◆ createForeignFileKit() [2/2]

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.

◆ canReadFile()

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

Checks if this concrete class can read the given file.

Reimplemented in SoSTLFileKit.

◆ readFile()

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 scene graph, call convert().

Reimplemented in SoSTLFileKit.

◆ canWriteFile()

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

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

Reimplemented in SoSTLFileKit.

◆ writeFile()

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

Writes the current contents to the given file.

See also
canWriteFile

Reimplemented in SoSTLFileKit.

◆ convert()

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.

◆ registerFileExtension()

SbBool SoForeignFileKit::registerFileExtension ( SoType  handler,
SbName  extension,
SoForeignFileIdentifyFunc *  identify 
)
staticprotected

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
