Examples of RandomAccessStream

com.caucho.vfs.RandomAccessStream
Reads from a file in a random-access fashion.
com.sun.midp.io.j2me.storage.RandomAccessStream
ij.io.RandomAccessStream
This is a class that uses a memory cache to allow seeking within an InputStream. Based on the JAI MemoryCacheSeekableStream class. Can also be constructed from a RandomAccessFile, which uses less memory since the memory cache is not required.
