Detailed Description

The SoMFEngine class is a container for engines.

This field container stores an array of pointers to engines. It takes care of the necessary functionality for handling copy, import and export operations.

Note that engine pointers stored in field instances of this type may be NULL pointers.

Member Function Documentation

◆ copyFrom()

void SoMFEngine::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.

◆ copyValue()

virtual void SoMFEngine::copyValue	(	int	to,
		int	from )

protectedvirtual

Implements SoMField.

◆ createInstance()

void * SoMFEngine::createInstance ( void )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Creates a new instance of the class type corresponding to the SoType object.

◆ deleteAllValues()

virtual void SoMFEngine::deleteAllValues ( void )

protectedvirtual

Implements SoMField.

◆ deleteValues()

virtual void SoMFEngine::deleteValues	(	int	start,
		int	numarg = -1 )

virtual

Remove value elements from index start up to and including index start + num - 1.

Elements with indices larger than the last deleted element will be moved downwards in the value array.

If num equals -1, delete from index start and to the end of the array.

Reimplemented from SoMField.

◆ fixCopy()

void SoMFEngine::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.

◆ getClassTypeId()

SoType SoMFEngine::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

◆ getTypeId()

SoType SoMFEngine::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and "downward" casting.

Implements SoField.

◆ getValues()

const SoEngine ** SoMFEngine::getValues ( const int start ) const

inline

Returns a pointer to the values array.

◆ initClass()

void SoMFEngine::initClass ( void )

static

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.

◆ insertSpace()

virtual void SoMFEngine::insertSpace	(	int	start,
		int	numarg )

virtual

Insert num "slots" for new value elements from start. The elements already present from start will be moved "upward" in the extended array.

Reimplemented from SoMField.

◆ isSame()

SbBool SoMFEngine::isSame ( const SoField & f ) const

virtual

Check for equal type and value(s).

Implements SoField.

◆ referencesCopy()

SbBool SoMFEngine::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 as well.

Reimplemented from SoField.
