    Default Record binary files

    Hi,

    In my project I need to record some structures into a binary files.

    some requirements:
    1. the recording need to be in a separate task (separate context)
    2. the size of each binary file need to be of X bytes (i.e one file can contains several records, and just when there are enough records a new file will be record)

    Is there an implementation of this in Java ? or Do I need to develop it by my own ?

    Thank's

    You'll need to develop it.

    Thank's

    Do you know if there is an implementation to those requirements in the net ?
    I know that there is an implementation for logger (log4j) and I thought maybe there is an implementation for this too ?
    THANKS AGAIN

    Sorry, I don't see how your requirements for what is written to a file would be any of use in another project.

    The propose of those requirements is to save write operations (it is better to write buffer of 1MB instead of 10 writes of 100K buffers)...

    I missed the discussion about buffering.
