Selector.ChildOrParentSelector.MatchingReferrerFinder (JOSM)

java.lang.Object
- org.openstreetmap.josm.gui.mappaint.mapcss.Selector.ChildOrParentSelector.MatchingReferrerFinder

All Implemented Interfaces:

PrimitiveVisitor

Enclosing class:

Selector.ChildOrParentSelector
```
private class Selector.ChildOrParentSelector.MatchingReferrerFinder
extends java.lang.Object
implements PrimitiveVisitor
```
Finds the first referrer matching Selector.ChildOrParentSelector.left

The visitor works on an environment and it saves the matching referrer in e.parent and its relative position in the list referrers "child list" in e.index.

If after execution e.parent is null, no matching referrer was found.
