.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. 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 * SoPackedColor::getFieldData (void) const\fC [protected]\fP, \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 "void SoPackedColor::doAction (\fBSoAction\fP *action)\fC [virtual]\fP"
This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoPackedColor::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.
.PP
This is called during rendering traversals\&. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoPackedColor::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.
.PP
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "SbBool SoPackedColor::isTransparent (void)"
Returns \fCTRUE\fP if there is at least one RGBA vector in the set which is not completely opaque\&. 
.SS "void SoPackedColor::notify (\fBSoNotList\fP *l)\fC [protected]\fP, \fC [virtual]\fP"
Notifies all auditors for this instance when changes are made\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SH "Member Data Documentation"
.PP 
.SS "\fBSoMFUInt32\fP SoPackedColor::orderedRGBA"
Set of packed 32-bit RGBA vectors\&.
.PP
The most significant 24 bits specifies 8 bits each for the red, green and blue components\&.
.PP
The least significant 8 bits specifies the transparency value, where 0x00 means completely transparent, and 0xff completely opaque\&.
