# SoLightPath(3)

The SoLightPath class is a light version of SoPath.

## NAME

SoLightPath - The **SoLightPath** class is a light version of **SoPath**.

## SYNOPSIS

\#include \<Inventor/misc/SoLightPath.h\>

## Detailed Description

The **SoLightPath** class is a light version of **SoPath**.

**SoLightPath** can be used if you only need a temporary path, and don't want the overhead that comes with an **SoPath** (ref, unref, auditing etc).

It is your responsibility to make sure the path is valid before using it.

## Constructor & Destructor Documentation

### SoLightPath::SoLightPath (SoNode \* headnodeptr, const int approxlength)

A constructor. Supply the head node and the approximate length of the path.

### SoLightPath::SoLightPath (const int approxlength)

A constructor. Supply the approximate length of the path.

### SoLightPath::~SoLightPath ()

Destructor.

## Member Function Documentation

### void SoLightPath::setHead (SoNode \*const node)

Sets head of path. Truncates path to length 1.

### void SoLightPath::append (const int childindex)

Appends a *childindex* to the path.

### void SoLightPath::push (const int childindex)

Same as **append()**.

### void SoLightPath::pop (void )

Pops off the last child.

### void SoLightPath::setTail (const int childindex)

Sets the tail of the path.

### SoNode \* SoLightPath::getTail (void ) const

Returns the tail node of the path. Uses **getNode()**.

### SoNode \* SoLightPath::getHead (void ) const

Returns the head node.

### SoNode \* SoLightPath::getNode (const int index) const

Returns the index'th node in path.

### int SoLightPath::getIndex (const int index) const

Returns the child index of the index'th node in the path.

### int SoLightPath::getFullLength () const

Returns the length of the path.

### void SoLightPath::truncate (const int startindex)

Truncates the path from *startindex*.

### void SoLightPath::makeTempPath (SoTempPath \* path) const

Updates *path* to be the same path as this path.
