Inheritance diagram for SoFieldContainer:
The classes containing fields in Coin are the node and engine classes, so they are all subclasses of SoFieldContainer.
SoFieldContainer provides methods for reading, writing, comparing for equality, doing copy operations, etc on fields.

This method sets all fields which we are parenting to their respective default values. |

This method checks to see if the fields of this container have their default values, and returns |
|
This method returns |
|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. This method copies the field values from container into this. The fields are assumed to be of the same type. The copyconnections flag decides whether the field connections are to be copied aswell. |
|
This method parses the values of one or more fields from the fielddata string.
The fields must be in the same format as the Open Inventor file format.
Reimplemented in SoBaseKit. |
|
This methods stores the field data in the given fielddata string. The format of the returned string follows the Open Inventor file format.
|
|
This method adds the fields in this container to the l argument, and returns the number of fields added. The virtual nature of this function means that it can be overridden to e.g. hide private fields. |
|
Returns VRML eventIn and eventOut fields in addition to the "ordinary" fields.
|
|
This method returns a pointer to the field with name, or |
|
This method returns a pointer to the eventIn with name name, or |
|
This method returns a pointer to the eventOut with name name, or |
|
Finds the name of the given field and returns the value in the name argument.
|
|
This method sets whether notification will be propagated on changing the values of the contained fields. The old value of the flag is returned. Notification is default on. Turning off automatic notification can be useful for optimizing performance. During series of updates you may want to avoid the propagation of notifications upon every field value change if you make a lot of them. This is how you should handle those cases:
SbBool autonotify = node->enableNotify(FALSE); // ... // Make modifications to fields of "node" here. // ... node->enableNotify(autonotify); node->touch();
|
|
This method returns whether notification of changes to the field values in the container is propagated to its auditors.
|
|
This method parses the values of one or more fields from the fielddata string.
The fields must be in the same format as the Open Inventor file format. We use the reference dictionary provided by in.
|
|
Put names and values of fields from this instance in the fielddata string. Fields will be separated in the returned string by end-of-line characters. We use the reference dictionary provided by out.

Notifies all auditors for this instance when changes are made. Reimplemented from SoBase.

|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. I can't make head or tails of this method, it seems to return TRUE no matter what the arguments are. |
|
This method is used during the first write pass of a write action to count the number of references to this object in the scene graph. Reimplemented from SoBase. Reimplemented in SoBaseKit. |
|
Writes all the fields contained in this instance to the output stream within out. This method is solely called from the write methods of fields. Either from SoField if the write is done because of a field-to-field connection, or from one of the fields which may actually write SoFieldContainer instances, i.e. SoSFNode, SoMFNode, SoSFEngine, SoMFEngine, SoSFPath and SoMFPath. This method, in addition to the ordinary write() method of SoNode, needs to be present since the fields don't have a write action instance in their writeValue() method, and writeInstance() will create a new SoWriteAction and call continueToApply() on it. Reimplemented in SoElapsedTime, SoEngine, SoTimeCounter, SoNodeEngine, and SoNode. |

Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is 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:
void MyCoinExtensionNode::copyContents(const SoFieldContainer * from, SbBool copyconnections) { // let parent superclasses do their thing (copy fields, copy // instance name, etc etc) SoNode::copyContents(from, copyconnections); // [..then copy internal data..] } Reimplemented in SoRotateCylindricalDragger, SoRotateSphericalDragger, SoClipPlaneManip, SoDirectionalLightManip, SoPointLightManip, SoSpotLightManip, SoTransformManip, SoBaseKit, SoInteractionKit, SoNodeKitListPart, SoCallback, SoFile, SoGroup, SoNode, SoWWWInline, SoVRMLAppearance, SoVRMLGeometry, SoVRMLLOD, SoVRMLParent, SoVRMLScript, SoVRMLShape, and SoVRMLSwitch. |

Return copy of this instance.
Note: default implementation just returns |
|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Initialize a dictionary hash storing pointers for original fieldcontainer instances and their copies during scene graph copy operations. This method is called from the start of SoNode::copy(). |
|
Add a pair of pointers to an original fieldcontainer and a copy of it to an internal pointer dictionary used during scene graph copy operations. |
|
Returns the copy of orig, if any. If no copy exists, we return a |
|
Returns a copy of orig. If no copy has been made earlier when the function is called, a copy is made on-the-fly (which is the reason we need to pass along the copyconnections flag). This method will also run the copyContents() method on the copy, if it hasn't been run already. Note that if you call copyContents() on the copy outside of this method, this will go undetected and the guts of orig will be copied multiple times into its copy. If copyContents() is called directly (instead of using copy()), it's assumed that the user only wants to copy the field values, and we just return NULL here. This is done to match how it's done in SGI Inventor.

|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Clean up the dictionary hash. This method is called from the end of SoNode::copy(). |
|
Set a generic user data pointer for this field container. This function can be used by the application programmer to, for instance, store a pointer to an application specific data structure that is in some way related to the field container. getUserData() can later be used to retrieve the pointer.
|
|
Return the generic user data pointer for this field container, or NULL if no user data has been set.

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.
flags is used internally during binary import when reading user extension nodes, group nodes or engines. Implements SoBase. Reimplemented in SoEngine, SoNodeEngine, SoBaseKit, SoInteractionKit, SoNodeKitListPart, SoBumpMap, SoFile, SoGroup, SoImage, SoNode, SoNormalBinding, SoSeparator, SoTexture2, SoTexture3, SoTextureCoordinateBinding, SoWWWInline, SoVRMLImageTexture, SoVRMLLOD, SoVRMLParent, SoVRMLPixelTexture, and SoVRMLSwitch. |
|
Flag for storing whether or not this class instance is a built-in class or not. By knowing the difference between a class which is native Coin or a user extension, it is possible to automatically store and read extension nodes and engines. |
