All Superinterfaces:

ByteBufferBackedDataInput, DataInput

All Known Implementing Classes:

SimpleFileInput
```
public interface FileInput
extends ByteBufferBackedDataInput
```
File input, backed by byte buffer file input. This class allows to read data by chunks from file and then read primitives.
