java.lang.Object
org.epics.archiverappliance.utils.nio.tar.TarReadOnlyByteChannel
All Implemented Interfaces:
Closeable, AutoCloseable, ByteChannel, Channel, ReadableByteChannel, SeekableByteChannel, WritableByteChannel
public class TarReadOnlyByteChannel extends Object implements SeekableByteChannel
Wraps a SeekableByteChannel to present a read only view of the tar entry. tar.dataoffset() is the offset of the start of the data in the tar file, and tar.size() is the size of the data. The position of the channel is relative to the start of the tar file, so we need to adjust the position and limit of the channel to present a view of the tar entry data.
