RandomAccessFile-like API for in-memory byte array?

Question

I need to replace code using RandomAccessFile with one that uses in-memory byte buffer (such as byte[] or derivatives like ByteArrayInputStre

Answer 1

I had the same problem. RandomAccessFile has many finale and native methods, so it cannot be overloaded.

I ended to create my own SeekableInputStream abstract class by stealing this one without readfully : https://github.com/samtools/htsjdk/blob/master/src/java/htsjdk/samtools/seekablestream/SeekableStream.java

I defined SeekableFileInputStream which uses RandomAccessFile.

I defined SeekableByteArrayInputStream, which is easy to define. This class, is also able to get any InputStream, to transform it into a byte array, so this is a kind of cached stream.
