SoShaderParameterArray4f.3coin4 - Man Page

virtual SoType getTypeId (void) const
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.
virtual void updateParameter (SoGLShaderObject *shaderObject)
Updates the shader parameter in the OpenGL state with the content of the value field.

static SoType getClassTypeId (void)
static void initClass ()

SoMFVec4f value

virtual const SoFieldData * getFieldData (void) const

static const SoFieldData ** getFieldDataPtr (void)

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 SoUniformShaderParameter.

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

Reimplemented from SoUniformShaderParameter.

Updates the shader parameter in the OpenGL state with the content of the value field.
