SoPickedPointList

NAME

SoPickedPointList -

SYNOPSIS

#include <Inventor/lists/SoPickedPointList.h>

Inherits SbPList.

Detailed Description

The SoPickedPointList class is a container for pointers to SoPickedPoint objects.

This list class will delete the picked points when destructed/truncated, or when a picked point in the list is replaced by another picked point The caller is responsible for allocating the picked points passed to the list, but should not deallocate them since this will be handled by the list.

Constructor & Destructor Documentation

SoPickedPointList::SoPickedPointList (void) [inline]

Default constructor.

SoPickedPointList::SoPickedPointList (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)

SoPickedPointList::SoPickedPointList (const SoPickedPointList & l)

Copy constructor. Will copy picked points, not just pointers.

See also:

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

References SbPList::copy(), and SbPList::getLength().

Member Function Documentation

SoPickedPoint * SoPickedPointList::operator[] (const int idx) const [inline]

Returns element at idx.

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

Reimplemented from SbPList.

References SbPList::operator[]().

void SoPickedPointList::truncate (const int start, const int fit = 0)

Overridden to delete truncated items.

Reimplemented from SbPList.

References SbPList::getLength(), and SbPList::truncate().

void SoPickedPointList::set (const int idx, SoPickedPoint * pp)

Overridden to destruct the replaced item.
