# SoPickedPointList(3iv)

maintains a list of pointers to SoPickedPoint instances

## NAME

SoPickedPointList — maintains a list of pointers to **SoPickedPoint** instances

## INHERITS FROM

SbPList \> SoPickedPointList

## SYNOPSIS

**#include \<Inventor/SoLists.h\>**

Methods from class SoPickedPointList:

	**SoPickedPointList()**\
 	**SoPickedPointList(int size)**\
 	**SoPickedPointList(const SoPickedPointList &l)**\
 	**~SoPickedPointList()**\
 **void**	**append(SoPickedPoint \*ptr)**\
 **void**	**insert(SoPickedPoint \*ptr, int addBefore)**\
 **void**	**truncate(int start)**\
 **SoPickedPoint \***	**operator \[\](int i) const**\
 **void**	**set(int i, SoPickedPoint \*pickedPoint)**

Methods from class SbPList:

**int**	**find(const void \*ptr) const**\
 **void**	**remove(int which)**\
 **int**	**getLength() const**\
 **void**	**copy(const SbPList &pl)**\
 **SbPList &**	**operator =(const SbPList &pl)**\
 **int**	**operator ==(const SbPList &pl) const**\
 **int**	**operator !=(const SbPList &pl) const**

## DESCRIPTION

**This subclass of SbPList** holds lists of pointers to instances of classes derived from **SoPickedPoint**. It is used primarily to return information from picking with the **SoRayPickAction** class.

## METHODS

	**SoPickedPointList()**\
 Constructor.

	**SoPickedPointList(int size)**\
 Constructor that pre-allocates storage for **size** pointers.

	**SoPickedPointList(const SoPickedPointList &l)**\
 Constructor that copies the contents of another list.

	**~SoPickedPointList()**\
 Destructor.

**void**	**append(SoPickedPoint \*ptr)**\
 Adds a pointer to the end of the list.

**void**	**insert(SoPickedPoint \*ptr, int addBefore)**\
 Inserts given pointer in list before pointer with given index.

**void**	**truncate(int start)**\
 Removes all pointers after one with given index, inclusive, deleting all instances removed from the list.

**SoPickedPoint \***	**operator \[\](int i) const**\
 Accesses an element of a list.

**void**	**set(int i, SoPickedPoint \*pickedPoint)**\
 Sets an element of a list.
