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.

SoLightPath::SoLightPath (\fBSoNode\fP *headnodeptr, const intapproxlength)

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

SoLightPath::SoLightPath (const intapproxlength)

A constructor. Supply the appriximate length of the path.

SoLightPath::~SoLightPath ()

Destructor.

void SoLightPath::setHead (\fBSoNode\fP *constnode)

Sets head of path. Truncates path to length 1.

void SoLightPath::append (const intchildindex)

Appends a childindex to the path.

void SoLightPath::push (const intchildindex)

Same as append().

void SoLightPath::pop (void)

Pops off the last child.

void SoLightPath::setTail (const intchildindex)

Sets the tail of the path.

\fBSoNode\fP * SoLightPath::getTail (void) const

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

\fBSoNode\fP * SoLightPath::getHead (void) const

Returns the head node.

\fBSoNode\fP * SoLightPath::getNode (const intindex) const

Returns the indexth node in path.

int SoLightPath::getIndex (const intindex) const

Returns the child index of the indexth node in the path.

int SoLightPath::getFullLength () const

Returns the length of the path.

void SoLightPath::truncate (const intstartindex)

Truncates the path from startindex.

void SoLightPath::makeTempPath (\fBSoTempPath\fP *path) const

Updates path to be the same path as this path.
