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:
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.

.

|
virtual |
Returns TRUE
if the node could have any effect on the state during traversal.
If it returns FALSE
, no data in the traversal-state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE
, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE
, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.
The default method returns TRUE
, on a "better safe than sorry" philosophy.

This method is mainly intended for internal use during file import operations.
It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.
TRUE
or FALSE
is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE
.
flags is used internally during binary import when reading user extension nodes, group nodes or engines.
Reimplemented from SoGroup.
References children, SoField::enableNotify(), and SoNode::readInstance().

protectedvirtual |
Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is FALSE
.
This is the protected method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.
For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:
The same also goes for engines.
Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:
