ElisionFilter (Lucene 2.9.4 API)

java.lang.Object
- org.apache.lucene.util.AttributeSource
- - org.apache.lucene.analysis.TokenStream
  - - org.apache.lucene.analysis.TokenFilter
    - - org.apache.lucene.analysis.fr.ElisionFilter

```
public class ElisionFilter
extends org.apache.lucene.analysis.TokenFilter
```
Removes elisions from a TokenStream. For example, "l'avion" (the plane) will be tokenized as "avion" (plane).
Note that StandardTokenizer sees " ' " as a space, and cuts it out.
