Description

This field maintains a pointer to an SoNode instance, correctly maintaining its reference count.

SoSFNodes are written to file as the node they are pointing to. For example:

mySoSFNodeField Cube {}

is an SoSFNode field named 'mySoSFNodeField', pointing 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 points to a node named 'topSeparator' that was DEF'ed earlier in the scene.

Methods

static SoType getClassTypeId()

virtual void getTypeId() const
Returns the type for this class or a particular object of this class.

SoNode * getValue() const
Returns this field's value.

SoNode * operator =(SoNode * newValue)

void setValue(SoNode * newValue)
Sets this field to newValue.

int operator ==(const SoSFNode &f) const

int operator !=(const SoSFNode &f) const
Returns TRUE if f is of the same type and has the same value as this field.
