NAME
SoSFNode
SYNOPSIS
#include <Inventor/fields/SoSFNode.h> Inherits SoSField.
Detailed Description
The SoSFNode class is a container for a single node.
This field container stores a pointer to a Coin node. It takes care of
the necessary functionality for handling copy, import and export
operations.
Note that the node pointer stored in a field instance of this type may
be a NULL pointer.

Member Function Documentation
- SoType SoSFNode::getClassTypeId (void) [static]
- Returns a unique type identifier for this field class.
- See also:
getTypeId(), SoType
- Reimplemented from SoSField.
- Referenced by SoTrackballDragger::metaKeyChangeCB().
- SoType SoSFNode::getTypeId (void) const [virtual]
- Returns the type identification instance which uniquely identifies the Coin field class the object belongs to.
- See also:
getClassTypeId(), SoType
- Implements SoField.
- void SoSFNode::copyFrom (const SoField & f) [virtual]
- Copy value(s) from f into this field. f must be of the same type as this field.
- Implements SoField.
- SbBool SoSFNode::isSame (const SoField & f) const [virtual]
- Check for equal type and value(s).
- Implements SoField.
- void SoSFNode::initClass (void) [static]
- Internal method called upon initialization of the library (from
SoDB::init()) to set up the type system. - Reimplemented from SoSField.
- Referenced by SoField::initClasses().
- void SoSFNode::fixCopy (SbBool copyconnections) [virtual]
- This method is internally called after SoField::copyFrom() during scene graph copies, and should do the operations necessary for fixing up the field instance after it has gotten a new value.
- The default method in the SoField superclass does nothing.
- The application programmer should normally not need to consider this
method, unless he constructs a complex field type which contains new
references to container instances (i.e. nodes or engines). Overriding
this method is then necessary to update the reference pointers, as they could have been duplicated during the copy operation. - Reimplemented from SoField.
- References SoBase::assertAlive(), SoNode::copy(), and
SoFieldContainer::findCopy(). - SbBool SoSFNode::referencesCopy (void) const [virtual]
- Returns TRUE if this field has references to any containers in the
scene graph which are also duplicated during the copy operation. - Note that this method only is valid to call during copy operations.
- See also the note about the relevance of the fixCopy() method for application programmers, as it is applicable on this method aswell.
- Reimplemented from SoField.
- References SoFieldContainer::checkCopy(), SoPath::getClassTypeId(),
SoEngine::getClassTypeId(), SoNode::getClassTypeId(),
SoPath::getHead(), SoBase::isOfType(), and SoField::referencesCopy().
