           run-time type checking and 'downward' casting.

Member Function Documentation

   SoType SoFragmentShader::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.

       Reimplemented from SoShaderObject.

   const SoFieldData * SoFragmentShader::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 SoShaderObject.

   SbBool SoFragmentShader::isSupported (SourceTypesourceType) [static]
       Returns a boolean indicating whether the requested source type is supported by the OpenGL driver or not.

       Beware: To get a correct answer, a valid OpenGL context must be available.
