Constructor Detail

RAF

public RAF(java.io.File f,
           java.lang.String mode)
    throws java.io.IOException

Method Detail

seekAndWrite

public void seekAndWrite(long pos,
                         byte[] b,
                         int off,
                         int len)
                  throws java.io.IOException

seekAndReadFully

public void seekAndReadFully(long pos,
                             byte[] b,
                             int off,
                             int len)
                      throws java.io.IOException

renameTo

public void renameTo(java.io.File destFile)
              throws java.io.IOException

This version of renameTo() attempts to mimic the behavior of the unix 'mv' command rather than File.renameTo. This means that the destFile will automatically be deleted if it exists and if we are unable to mv the file directly because they are on different file systems then we will manually copy and delete the original. If there is an exception during the copy then we will attempt to delete the new copy and leave the old copy intact.

getMode

public java.lang.String getMode()

setReadOnly

public void setReadOnly()
                 throws java.io.IOException

setLength

public void setLength(long len)
               throws java.io.IOException

close

public void close()
           throws java.io.IOException
