This is used for run-time type checking and 'downward' casting\&. Usage example: .PP .PP .nf void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } } .fi .PP .PP For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&. .PP For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. .PP Implements \fBSoBase\fP\&. .SS "const \fBSoFieldData\fP * SoOnOff::getFieldData (void) const\fC [virtual]\fP" Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. .PP Reimplemented from \fBSoFieldContainer\fP\&. .SS "const \fBSoEngineOutputData\fP * SoOnOff::getOutputData (void) const\fC [virtual]\fP" \fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP .PP Implements \fBSoEngine\fP\&. .SH "Member Data Documentation" .PP .SS "\fBSoSFTrigger\fP SoOnOff::on" An input signal on this trigger makes the \fBSoOnOff::isOn\fP output become \fCTRUE\fP\&. .SS "\fBSoSFTrigger\fP SoOnOff::off" An input signal on this trigger makes the \fBSoOnOff::isOn\fP output become \fCFALSE\fP\&. .SS "\fBSoSFTrigger\fP SoOnOff::toggle" An input signal on this trigger toggles the \fCTRUE\fP or \fCFALSE\fP value of the \fBSoOnOff::isOn\fP output\&. .SS "\fBSoEngineOutput\fP SoOnOff::isOn" (\fBSoSFBool\fP) Whether the engine is 'on' or not\&. .SS "\fBSoEngineOutput\fP SoOnOff::isOff" (\fBSoSFBool\fP) Always the opposite value of \fBSoOnOff::isOn\fP\&. .SH "Author" .PP Generated automatically by Doxygen for Coin from the source code\&.
