Field containing a a node.
This field maintains a an SoNode instance , correctly maintaining its reference counts .
SoSFNodes are written to file as the node they are containing. For example:
mySoSFNodeField Cube {}
is an SoSFNode field named 'mySoSFNodeField', referring to an SoCube node. If the node is used elsewhere, the regular DEF/USE instancing mechanism applies:
anotherSoSFNodeField USE topSeparator
is an SoSFNode field that refers to a node named 'topSeparator' that was DEF'ed earlier in the scene.

SoSFNode::SoSFNode | ( | ) |
Default constructor.

Returns the type identifier for this class.
|
virtual |
Returns the type identifier for this specific instance.
Implements SoTypedObject.
|
inline |
Returns this field's value.
Definition at line 100 of file SoSFNode.h.
Gets the value of this field.
The getEffectiveNode parameter is only used when the node in the field is a Proto. In this case, if the parameter is true then for convenience it returns the first child of the proto (the node the proto is pretending to be).
