## Detailed Description

The **SbVec3fList** class is a container for pointers to **SbVec3f** objects.

Note that upon using the equality and inequality operators, the **SbVec3f** objects themselves are not compared, only the pointer values.

Note also that all calls to **append()** and **insert()** will cause the list to allocate a new **SbVec3f** object. These objects are freed when the list is destructed.

## Constructor & Destructor Documentation

### SbVec3fList::SbVec3fList (void ) \[inline\]

Default constructor.

### SbVec3fList::~SbVec3fList ()

Destructor.

## Member Function Documentation

### void SbVec3fList::append (const SbVec3f \* item) \[inline\]

Append *item* to the end of the list.

Automatically allocates more items internally if needed.

Overloaded from parent to allocate a new **SbVec3f** instance when called.

**See also**

**SbPList::append()**

### void SbVec3fList::insert (const SbVec3f \* item, const int insertbefore) \[inline\]

Insert *item* at index *insertbefore*.

*insertbefore* should not be larger than the current number of items in the list.

Overloaded from parent to allocate a new **SbVec3f** instance when called.

**See also**

**SbPList::insert()**

### SbVec3f \* SbVec3fList::operator\[\] (const int idx) const \[inline\]

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 **SbVec3f** pointer.

**See also**

**SbPList::operator\[\]()**
