Class PrefixTree

java.lang.Object

org.eclipse.aether.internal.impl.filter.ruletree.PrefixTree

public class PrefixTree
extends Object

Prefix tree for paths: if you step on a path prefix that exists, you are good to go. This class parses a text file that has a prefix on each line:

• ignored/formatting - each line starting with '#' (hash) or being empty/blank is ignored.
• a path prefix ie "/org/apache/maven".

By default, artifact is allowed if layout converted path of it has a matching prefix in this file.

Example prefix files:

• Maven Central
• ASF Releases
• Eclipse Tycho
