Class BufferedRandomAccessFile

java.lang.Object

java.io.InputStream

com.github.dagnelies.filemap.BufferedRandomAccessFile

All Implemented Interfaces:

Closeable, AutoCloseable

public class BufferedRandomAccessFile
extends InputStream

In core Java, you have the choice between: - RandomAccessFile: random access but slow (unbuffered) - BufferedInputStream/Reader: fast (buffered) but no random access Sadly, both are incompatible and there is no meaningful way to combine them. This is the reason of this BufferedRandomAccessFile. To provide random access along with fast read capabilities thanks to buffering.
