Class SeekableInputStream

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

org.apache.commons.io.input.ProxyInputStream

net.sansa_stack.hadoop.util.SeekableInputStream

All Implemented Interfaces:

Closeable, AutoCloseable, SeekableDecorator, org.apache.hadoop.fs.Seekable

public class SeekableInputStream
extends org.apache.commons.io.input.ProxyInputStream
implements SeekableDecorator

A basic wrapper that combines Hadoop's Seekable and InputStream into one class. Because InputStream is not an interface we have to work which such a wrapper class if we want the methods of both combined.

SeekableInputStream

public SeekableInputStream(InputStream in,
 org.apache.hadoop.fs.Seekable seekable)

Constructs a new ProxyInputStream.

Method Details

getSeekable

public org.apache.hadoop.fs.Seekable getSeekable()

You should not change the position of the underlying seekable directly while this input stream is in use. Conversely, only use this class' seek methods for changing the position. Otherwise it my result in an inconsistent state.

Specified by:

getSeekable in interface SeekableDecorator

Returns:

The underlying seekable.
