FastLineIterator (druid-processing 30.0.1 API)

java.lang.Object
- org.apache.druid.data.input.impl.FastLineIterator<T>

All Implemented Interfaces:

Closeable, AutoCloseable, Iterator<T>, CloseableIterator<T>

Direct Known Subclasses:

FastLineIterator.Bytes, FastLineIterator.Strings
```
public abstract class FastLineIterator<T>
extends Object
implements CloseableIterator<T>
```
Like the Apache Commons LineIterator, but faster. Use FastLineIterator.Strings or FastLineIterator.Bytes as appropriate. Bytes is faster.
