NAME

SoFieldContainer

SYNOPSIS

#include <Inventor/fields/SoFieldContainer.h>
Inherits SoBase.
Inherited by SoEngine, and SoNode.

Detailed Description

The SoFieldContainer class is a base class for all classes that contain fields.

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.

int SoFieldContainer::getFields (SoFieldList & fields) const [virtual]

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.

SbBool SoFieldContainer::enableNotify (const SbBool enable)

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();

void SoFieldContainer::writeInstance (SoOutput * out) [virtual]

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.

void SoFieldContainer::copyContents (const SoFieldContainer * from, SbBool

copyconnections) [virtual] Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is FALSE.

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:

SoNode * mynewnode = templatenode->copy();

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..]

}

SoFieldContainer * SoFieldContainer::findCopy (const SoFieldContainer *

orig, const SbBool copyconnections) [static] 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.

void SoFieldContainer::copyDone (void) [static]

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().

void SoFieldContainer::setUserData (void * userdata) const

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.

SbBool SoFieldContainer::readInstance (SoInput * in, unsigned short flags)

[protected, virtual]
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.

TRUE or FALSE is returned, depending on if the instantiation and
configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by
returning FALSE.

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, SoTextureCubeMap, SoShaderObject, SoWWWInline, SoVRMLImageTexture, SoVRMLLOD, SoVRMLParent, SoVRMLPixelTexture, and SoVRMLSwitch.

SbBool SoFieldContainer::isBuiltIn [protected]

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.
