Examples of IRandomAccessFile

net.sf.joafip.file.service.IRandomAccessFile
interface for random access in file
cache is maintained in memory independently to file opened state or closed state. useful when closing and reopening the file to ensure the data are write, then data in cache reflecting file content is not loose
