Detailed Description

SoFieldContainer is the abstract base class for engines and nodes. It contains methods for finding out what fields an object has, controlling notification, and for dealing with all of the fields of an object at once.

The fields of an engine are its inputs. Note that even though an engine's output corresponds to a specific type of field, an engine output is not a field.

Member Function Documentation

◆ addCopy()

static void SoFieldContainer::addCopy	(	const SoFieldContainer *	orig,
		const SoFieldContainer *	copy
	)

static

◆ addManagedSensor()

void SoFieldContainer::addManagedSensor ( SoSensor * sensor )

It will be deleted when the container is deleted.

◆ addWriteReference()

virtual void SoFieldContainer::addWriteReference	(	SoOutput *	out,
		bool	isFromField = `FALSE`
	)

virtual

isFromField indicates whether the reference is from a field-to-field connection.

Reimplemented from SoBase.

Reimplemented in SoBaseKit.

◆ checkCopy()

static SoFieldContainer* SoFieldContainer::checkCopy ( const SoFieldContainer * orig )

static

Otherwise, it returns NULL. The copy is not changed in any way.

◆ copyContents()

virtual void SoFieldContainer::copyContents	(	const SoFieldContainer *	fromFC,
		bool	copyConnections
	)

virtual

The default implementation copies just field values and the name.

Reimplemented in SoUnknownNode, SoUnknownEngine, SoWWWInline, SoNode, SoGroup, SoFile, SoCallback, SoNodeKitListPart, SoInteractionKit, SoBaseKit, SoTransformManip, SoSpotLightManip, SoPointLightManip, SoDirectionalLightManip, SoRotateSphericalDragger, and SoRotateCylindricalDragger.

◆ copyDone()

static void SoFieldContainer::copyDone ( )

static

◆ copyFieldValues()

void SoFieldContainer::copyFieldValues	(	const SoFieldContainer *	fc,
		bool	copyConnections = `FALSE`
	)

fc must be the same type as this object. If copyConnections is TRUE, then if any of fc's fields are connected then this object's fields will also be connected to the same source.

◆ copyThroughConnection()

virtual SoFieldContainer* SoFieldContainer::copyThroughConnection ( ) const

virtual

The default implementation just returns the original pointer - no copy is done. Subclasses such as nodes and engines handle this differently.

Reimplemented in SoNode, SoSelectOne, SoGate, SoEngine, and SoConcatenate.

◆ enableNotify()

bool SoFieldContainer::enableNotify ( bool flag )

inline

The returned boolean value indicates whether notification was enabled immediately prior to applying this method.

Definition at line 163 of file SoFieldContainer.h.

◆ fieldsAreEqual()

bool SoFieldContainer::fieldsAreEqual ( const SoFieldContainer * fc ) const

If fc is not exactly same type as this object, FALSE is returned.

◆ findCopy()

static SoFieldContainer* SoFieldContainer::findCopy	(	const SoFieldContainer *	orig,
		bool	copyConnections
	)

static

Otherwise, this copies the contents of the original into the copy (if not already done) and returns a pointer to the copy.

◆ get() [1/2]

void SoFieldContainer::get ( SbString & fieldDataString )

inline

Fields whose isDefault() bit is set will not be part of the string. You can use the field->get() method to get a field's value as a string even if has its default value.

Definition at line 140 of file SoFieldContainer.h.

◆ get() [2/2]

void SoFieldContainer::get	(	SbString &	fieldDataString,
		SoOutput *	dictOut
	)

Fields whose isDefault() bit is set will not be part of the string. You can use the field->get() method to get a field's value as a string even if has its default value.

◆ getClassTypeId()

static SoType SoFieldContainer::getClassTypeId ( )

inlinestatic

Definition at line 97 of file SoFieldContainer.h.

◆ getField()

virtual SoField* SoFieldContainer::getField ( const SbName & fieldName ) const

virtual

If no such field exists, NULL is returned.

◆ getFieldData()

virtual const SoFieldData* SoFieldContainer::getFieldData ( ) const

virtual

Objects with no fields should return NULL, which is what the default method does.

◆ getFieldName()

bool SoFieldContainer::getFieldName	(	const SoField *	field,
		SbName &	fieldName
	)		const

Returns FALSE if field is not a member of this object.

◆ getFields()

virtual int SoFieldContainer::getFields ( SoFieldList & list ) const

virtual

The types of the fields can be determined using field->isOfType() and field->getTypeId(), and their names can be determined by passing the field pointers to the getFieldName() method (see below).

◆ getIsBuiltIn()

bool SoFieldContainer::getIsBuiltIn ( ) const

inline

Used during writing.

Definition at line 227 of file SoFieldContainer.h.

◆ hasDefaultValues()

bool SoFieldContainer::hasDefaultValues ( ) const

This will return TRUE even if a field's isDefault() method returns FALSE em for example, if a field's default value is 0.0 and you setValue(0.0) that field, the default flag will be set to FALSE (because it would be too slow to compare the field against its default value every time setValue is called). However, hasDefaultValues() would return TRUE in this case.

◆ initClass()

static void SoFieldContainer::initClass ( )

static

◆ initCopyDict()

static void SoFieldContainer::initCopyDict ( )

static

These methods operate on that dictionary. Initializes a new copy dictionary

◆ isNotifyEnabled()

bool SoFieldContainer::isNotifyEnabled ( ) const

inline

Notification is needed to make engines and sensors function, is used to keep SoPaths up to date when the scene graph's topology changes, and is also used to invalidate rendering or bounding box caches.

Notification is normally enabled, but can be disabled on a node by node (or engine by engine) basis. If you are making extensive changes to a large part of the scene graph then disabling notification can increase performance, at the expense of increased responsibility for making sure that any interested engines, sensors or paths are kept up to date.

For example, if you will be making a lot of changes to a small part of your scene graph and you know that there are no engines or sensors attached to nodes in that part of the scene graph, you might disable notification on the nodes you are changing, modify them, re-enable notification, and then touch() one of the nodes to cause a redraw.

However, you should profile your application and make sure that notification is taking a significant amount of time before going to the trouble of manually controlling notification.

Definition at line 190 of file SoFieldContainer.h.

◆ notify()

virtual void SoFieldContainer::notify ( SoNotList * )

virtual

Reimplemented from SoBase.

Reimplemented in SoVertexShape, SoSeparator, SoNode, SoIndexedShape, SoEngine, and SoBlinker.

◆ readInstance()

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

protectedvirtual

Implements SoBase.

Reimplemented in SoUnknownNode, SoWWWInline, SoTextureCoordinateBinding, SoTexture2, SoSeparator, SoNormalBinding, SoMaterialBinding, SoGroup, SoFile, SoNodeKitListPart, SoInteractionKit, SoBaseKit, SoTimeCounter, SoOneShot, SoEngine, and SoElapsedTime.

◆ set() [1/2]

bool SoFieldContainer::set ( const char * fieldDataString )

inline

TRUE is returned if the string was valid Inventor file format. For example, you could set the fields of an SoCube by doing:

SoCube *cube = ....

cube->set("width 1.0 height 2.0 depth 3.2");

SoCube

Cube shape node.

Definition: SoCube.h:119

SoFieldContainer::set

bool set(const char *fieldDataString)

Sets one or more fields in this object to the values specified in the given string,...

◆ set() [2/2]

bool SoFieldContainer::set	(	const char *	fieldDataString,
		SoInput *	dictIn
	)

TRUE is returned if the string was valid Inventor file format. For example, you could set the fields of an SoCube by doing:

SoCube *cube = ....

cube->set("width 1.0 height 2.0 depth 3.2");

◆ setToDefaults()
