## 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() [1/2]

SoLightPath::SoLightPath | ( | SoNode * | headnodeptr,
|  | const int | approxlength )

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

## SoLightPath() [2/2]

SoLightPath::SoLightPath | ( | const int | approxlength | ) |

A constructor. Supply the approximate length of the path.

## ~SoLightPath()

SoLightPath::~SoLightPath | ( |  | ) |

Destructor.

## Member Function Documentation

## setHead()

void SoLightPath::setHead | ( | SoNode *const | node | ) |

Sets head of path. Truncates path to length 1.

## append()

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

Appends a childindex to the path.

## push()

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

Same as append().

## pop()

void SoLightPath::pop | ( | void |  | ) |

Pops off the last child.

## setTail()

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

Sets the tail of the path.

## getTail()

SoNode * SoLightPath::getTail | ( | void |  | ) | const

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

## getHead()

SoNode * SoLightPath::getHead | ( | void |  | ) | const

Returns the head node.

## getNode()

SoNode * SoLightPath::getNode | ( | const int | index | ) | const

Returns the index'th node in path.

## getIndex()

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

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

## getFullLength()

int SoLightPath::getFullLength | ( |  | ) | const

Returns the length of the path.

## truncate()

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

Truncates the path from startindex.

## makeTempPath()

void SoLightPath::makeTempPath | ( | SoTempPath * | path | ) | const

Updates path to be the same path as this path.
