## Constructor & Destructor Documentation

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

Default constructor.

### SoTypeList::SoTypeList (const int sizehint) \[inline\]

This constructor initializes the internal allocated size for the list to *sizehint*. Note that the list will still initially contain zero items.

**See also**

**SbList::SbList(const int sizehint)**

### SoTypeList::SoTypeList (const SoTypeList & l) \[inline\]

Copy constructor.

**See also**

**SbList::SbList(const SbList\<Type\> & l)**

## Member Function Documentation

### void SoTypeList::append (const SoType type)

Append *item* to the end of the list.

Automatically allocates more items internally if needed.

Overloaded from parent to accept an **SoType** pointer argument.

**See also**

**SbPList::append()**

### int SoTypeList::find (const SoType type) const

Return index of first occurrence of *item* in the list, or -1 if *item* is not present.

Overloaded from parent to accept an **SoType** argument.

**See also**

**SbPList::find()**

### void SoTypeList::insert (const SoType type, const int insertbefore)

Insert *item* at index *insertbefore*.

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

Overloaded from parent to accept an **SoType** argument.

**See also**

**SbPList::insert()**

### SoType SoTypeList::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 **SoType** instance.

**See also**

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

### void SoTypeList::set (const int index, const SoType item)

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

Overloaded from parent to accept an **SoType** argument.

**See also**

**SbPList::set()**
