List of fillBytesRef() Examples

Examples of fillBytesRef()

org.apache.lucene.analysis.tokenattributes.TermToBytesRefAttribute.fillBytesRef()
Updates the bytes {@link #getBytesRef()} to contain this term'sfinal encoding, and returns its hashcode. @return the hashcode as defined by {@link BytesRef#hashCode}:
```
 int hash = 0; for (int i = termBytes.offset; i < termBytes.offset+termBytes.length; i++) { hash = 31*hash + termBytes.bytes[i]; } 
```
Implement this for performance reasons, if your code can calculate the hash on-the-fly. If this is not the case, just return {@code termBytes.hashCode()}.
