GUIRunner.TreePathIterator (TestHelpers 1.1-SNAPSHOT API)

java.lang.Object
- eu.simuline.testhelpers.GUIRunner.TreePathIterator

Enclosing class:

GUIRunner
```
static class GUIRunner.TreePathIterator
extends Object
```
Represents a path currPath in the tree of testsuites represented by treeModel. This is initialized by setFirstPath() to the uppermost complete path, can be incremented via incPath() and be returned by getPath().

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`(package private) TreePath`	`getPath()`
`(package private) TreePath`	`incPath()`	Increments `currPath` and returns the result.
`(package private) static TreePath`	`prolonguePath(TreePath path)`	Prolongues path as long as possible in each step with 0th child.
`(package private) void`	`setFirstPath()`	Initializes `currPath` with the first path in `treeModel`. ** Shall be invoked by TreePathUpdater only **
`private int`	`shortenPath()`	Replaces `currPath` removing the last node as long as the last node in the path is the last child of the last but one node and after having done this returns the index of the last node as a child of the last but one node.
