This field container stores an array of pointers to paths. It takes care of the necessary functionality for handling copy, import and export operations.
Note that path pointers stored in field instances of this type may be NULL
pointers.
SoType SoMFPath::getClassTypeId | ( | void | ) | [static] |
Returns a unique type identifier for this field class.
Reimplemented from SoMField.
SoType SoMFPath::getTypeId | ( | void | ) | const [virtual] |
Returns the type identification instance which uniquely identifies the Coin field class the object belongs to.
Implements SoField.
void SoMFPath::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.
SbBool SoMFPath::isSame | ( | const SoField & | f | ) | const [virtual] |
Check for equal type and value(s).
Implements SoField.
const SoPath* * SoMFPath::getValues | ( | const int | start | ) | const [inline] |
\ Returns a pointer to the values array. \
void SoMFPath::initClass | ( | void | ) | [static] |
Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.
Reimplemented from SoMField.
void SoMFPath::notify | ( | SoNotList * | nlist | ) | [virtual] |
Notify auditors that this field has changed.
Reimplemented from SoField.
References SoBase::addAuditor(), SoPath::getHead(), SoMField::getNum(), SoField::notify(), SoBase::ref(), SoBase::removeAuditor(), and SoBase::unref().
void SoMFPath::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.
References SoBase::assertAlive(), SoPath::copy(), SoField::enableNotify(), SoFieldContainer::findCopy(), SoMField::getNum(), and SoField::valueChanged().
SbBool SoMFPath::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 aswell.
Reimplemented from SoField.
References SoFieldContainer::checkCopy(), SoMField::getNum(), and SoField::referencesCopy().
virtual void SoMFPath::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.
virtual void SoMFPath::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.
