Public Member Functions

virtual void fixCopy (bool copyConnections)
 Update a copied field to use the copy of each node if there is one.
 
virtual bool referencesCopy () const
 Override this to also check the stored nodes.
 
- Public Member Functions inherited from SoMField
virtual ~SoMField ()
 Destructor.

void setNum (int num)
 Forces this field to have exactly num values, inserting or deleting values as necessary.
 
virtual void deleteValues (int start, int num=-1)
 Deletes num values beginning at index start (index start through start+num-1 will be deleted, and any leftover values will be moved down to fill in the gap created).
 
virtual void insertSpace (int start, int num)
 Inserts space for num values at index start.
 
bool set1 (int index, const char *valueString)
 This is equivalent to the set() method of SoField, but operates on only one value.
 
void get1 (int index, SbString &valueString)
 This is equivalent to the get() method of SoField, but operates on only one value.
 
- Public Member Functions inherited from SoField
virtual ~SoField ()
 Destructor.

 Gets the state of default flag of the field.
 
virtual SoType getTypeId () const =0
 Return the type identifier for this field instance (SoField *).
 
bool isOfType (SoType type) const
 Returns TRUE if this field is the given type or derived from that type.
 
void enableConnection (bool flag)
 Field connections may be enabled and disabled.
 
bool isConnectionEnabled () const
 Returns FALSE if connections to this field are disabled.
 
bool connectFrom (SoEngineOutput *engineOutput)
 Connects the field to the given output of an engine or to another field.
 
bool connectFrom (SoField *field)
 
void disconnect ()
 Disconnect the field from whatever it was connected to.
 
bool isConnected () const
 Returns TRUE if the field is connected to anything.

 Returns TRUE if the field is connected to an engine's output.
 
bool isConnectedFromField () const
 Returns TRUE if the field is connected to another field.
 
bool getConnectedEngine (SoEngineOutput *&engineOutput) const
 Returns TRUE if this field is being written into by an engine, and returns the engine output it is connected to in engineOutput.
 
bool getConnectedField (SoField *&field) const
 Returns TRUE if this field is being written into by another field, and returns the field it is connected to in writingField.
 
int getForwardConnections (SoFieldList &list) const
 Adds pointers to all of the fields that this field is writing into (either fields in nodes, global fields or engine inputs) to the given field list, and returns the number of forward connections.
 
SoFieldContainer * getContainer () const
 Returns the containing node or engine.
 
bool set (const char *valueString)
 Sets the field to the given value, which is an ASCII string in the Inventor file format.
 
void get (SbString &valueString)
 Returns the value of the field in the Inventor file format, even if the field has its default value.
 
virtual void touch ()
 Simulates a change to the field, causing attached sensors to fire, connected fields and engines to be marked as needing evaluation, and so forth.
 
bool operator== (const SoField &f) const
 Return TRUE (FALSE) if this field is of the same type and has the same value as f.
 
bool operator!= (const SoField &f) const
 Return TRUE (FALSE) if this field is of the same type and has the same value as f.
 
void setDefault (bool def)
 Sets default flag.
 
virtual void startNotify ()
 Initiates or propagates notification through container.
 
virtual void notify (SoNotList *list)
 
void setContainer (SoFieldContainer *cont)
 Sets the containing node.
 
bool shouldWrite () const
 Returns TRUE if the field really needs to be written out.
 
void addAuditor (void *auditor, SoNotRec::Type type)
 Adds/removes an auditor to/from list.
 
void removeAuditor (void *auditor, SoNotRec::Type type)
 
bool enableNotify (bool flag)
 Indicates whether notification will propagate as the result of setting the field value.
 
bool isNotifyEnabled () const
 
bool enableContainerNotify (bool flag)
 Indicates whether notification will propagate to the SoFieldContainer that owns the field.
 
bool isContainerNotifyEnabled () const
 
virtual void connectionStatusChanged (int numConnections)
 Indicates to a field that a change has been made involving a connection from it (as source) to another field.
 
bool isReadOnly () const
 If this returns TRUE, it means we're in the middle of doing a setValue()+valueChanged() and values from an upstream connection shouldn't write into this field.
 
virtual bool isSame (const SoField &f) const =0
 Returns TRUE if the given field is of the same type and has the same value(s) as this.
 
virtual void copyFrom (const SoField &f)=0
 Copies the value from one field to another, assuming same subclass.
 
virtual void fixCopy (bool copyConnections)
 After a field value has been copied using copyFrom(), this is called to allow fields to update the copy.
 
virtual bool referencesCopy () const

Detailed Description

This field maintains a set of pointers to SoNode instances, correctly maintaining their reference counts.

SoMFNodes are written to file as one or more nodes. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:

[ Cube { }, Sphere { radius 2.0 }, USE myTranslation ]
