## Detailed Description

The SoBaseList class is a container for pointers to SoBase derived objects.

The additional capability of the SoBaseList class over its parent class, SbPList, is to automatically handle referencing and dereferencing of items as they are added or removed from the lists.

## Constructor & Destructor Documentation

## SoBaseList() [1/3]

SoBaseList::SoBaseList | ( | void |  | ) |

Default constructor.

## SoBaseList() [2/3]

SoBaseList::SoBaseList | ( | const int | size | ) |

Constructor with a hint about the maximum number of pointers in the list.

See also
  SbPList::SbPList(const int)

## SoBaseList() [3/3]

SoBaseList::SoBaseList | ( | const SoBaseList & | l | ) |

Copy constructor.

Shallow copy the items of l into this list, adding to the item reference counts if the reference flag of l is `TRUE`.

See also
  SbPList::SbPList(const SbPList &)

## ~SoBaseList()

SoBaseList::~SoBaseList | ( |  | ) |

Destructor. Dereferences items before freeing resources.

## Member Function Documentation

## append()

void SoBaseList::append | ( | SoBase * | ptr | ) |

Append ptr to list, adding to the reference count of the object (unless addReferences() has been set to `FALSE`).

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::append()

## insert()

void SoBaseList::insert | ( | SoBase * | ptr,
|  | const int | addbefore )

Insert ptr in the list at position addbefore, adding to the reference count of the object (unless addReferences() has been set to `FALSE`).

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::insert()

## remove()

void SoBaseList::remove | ( | const int | index | ) |

Removes item at index from the list, dereferencing the object (unless addReferences() has been set to `FALSE`).

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::remove()

## removeItem()

void SoBaseList::removeItem | ( | SoBase * | item | ) |

Removes item from the list, dereferencing the object (unless addReferences() has been set to `FALSE`).

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::removeItem()

## truncate()

void SoBaseList::truncate | ( | const int | length | ) |

Makes the list contain only the length first items, removing all items from index length and onwards to the end of the list. Dereferences the objects to be removed (unless addReferences() has been set to `FALSE`).

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::truncate()

## copy()

void SoBaseList::copy | ( | const SoBaseList & | l | ) |

Shallow copy of the item pointers of l list into this one, first removing all items in this list.

## operator=()

SoBaseList & SoBaseList::operator= | ( | const SoBaseList & | l | ) |

Shallow copy of the SoBase pointers from l into this one, returning a pointer to ourself.

See also
  copy()

## operator[]()

SoBase * SoBaseList::operator[] | ( | const int | idx | ) | const

Returns element at index.

Will automatically expand the size of the internal array if index is outside the current bounds of the list. The values of any additional pointers are then set to `NULL`.

Overloaded from parent to return an SoBase pointer.

See also
  SbPList::operator[]()

## set()

void SoBaseList::set | ( | const int | i,
|  | SoBase *const | ptr )

Index operator to set element at index. Does not expand array bounds if index is outside the list.

Overloaded from parent to support reference counting on the SoBase object.

See also
  SbPList::set(const int idx, void * item)

## addReferences()

void SoBaseList::addReferences | ( | const SbBool | flag | ) |

Decide whether or not the SoBase items should be automatically referenced and dereferenced as they are added and removed from the list.

Default setting is to do referencing.

## isReferencing()

SbBool SoBaseList::isReferencing | ( | void |  | ) | const

Return whether the SoBase instances are automatically referenced and dereferenced when they are added and removed from the list.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
