Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`append(SoBaseKit childKit)` Adds childKit to end of chain.
`void`	`append(SoPath fromPath)` Adds all nodekits in fromPath's chain to end of chain.
`boolean`	`containsNode(SoBaseKit nodekit)` Returns true if the nodekit is found anywhere in the path chain.
`boolean`	`containsPath(SoPath path)` Returns true if the nodes in the given path argument are contained (in consecutive order) in this path.
`int`	`findFork(SoPath path)` If the two paths have different head nodes, this returns -1.
`SoNode`	`getHead()` Return the first node in a path chain
`int`	`getLength()` Returns length of path chain (number of nodekits).
`SoNode`	`getNode(int i)` Return the i'th nodekit in the chain.
`SoNode`	`getNodeFromTail(int i)` Return the i'th nodekit in the chain, counting backward from the tail node.
`SoNode`	`getTail()` Return the last nodekit in a path chain.
`void`	`pop()` Pop the last nodekit off the end of the path.
`void`	`setHead(SoNode node)` Sets head node (first node in chain).
`void`	`truncate(int start)` Truncates the path chain, removing all nodes from index start on.

- Method Detail
  - setHead
```
void setHead(SoNode node)
```
    Sets head node (first node in chain). The head node must be set before the append() method may be called.
  - getHead
```
SoNode getHead()
```
    Return the first node in a path chain
  - append
```
void append(SoBaseKit childKit)
```
    Adds childKit to end of chain. Uses first occurrence of childKit as a part within current last nodekit. If the path is empty, this is equivalent to setHead(childKit).
  - append
```
void append(SoPath fromPath)
```
    Adds all nodekits in fromPath's chain to end of chain. The head node of fromPath must be the same as or a child of the current tail node.
  - pop
```
void pop()
```
    Pop the last nodekit off the end of the path.
  - getTail
```
SoNode getTail()
```
    Return the last nodekit in a path chain.
  - getNode
```
SoNode getNode(int i)
```
    Return the i'th nodekit in the chain. Calling getNode(0) is equivalent to calling getHead().
  - getNodeFromTail
```
SoNode getNodeFromTail(int i)
```
    Return the i'th nodekit in the chain, counting backward from the tail node. Calling getNodeFromTail(0) is equivalent to calling getTail().
  - getLength
```
int getLength()
```
    Returns length of path chain (number of nodekits).
  - truncate
```
void truncate(int start)
```
    Truncates the path chain, removing all nodes from index start on. Calling truncate(0) empties the path entirely.
  - containsNode
```
boolean containsNode(SoBaseKit nodekit)
```
    Returns true if the nodekit is found anywhere in the path chain.
  - containsPath
```
boolean containsPath(SoPath path)
```
    Returns true if the nodes in the given path argument are contained (in consecutive order) in this path.
  - findFork
```
int findFork(SoPath path)
```
    If the two paths have different head nodes, this returns -1. Otherwise, it returns the path chain index of the last nodekit (starting at the head) that is the same for both paths.
