VectorSet (Apache Ant API)

- java.util.AbstractCollection<E>
- - java.util.AbstractList<E>
  - - java.util.Vector<E>
    - - org.apache.tools.ant.util.VectorSet<E>

```
public final class VectorSet<E>
extends java.util.Vector<E>
```
Subclass of Vector that won't store duplicate entries and shows HashSet's constant time performance characteristics for the contains method.
This is not a general purpose class but has been written because the protected members of DirectoryScanner prohibited later revisions from using a more efficient collection.

Methods are synchronized to keep Vector's contract.

Since:

Ant 1.8.0
