  • Method Details

    • getFilePointer

      long getFilePointer() throws IOException
      Returns the current offset in this file.
      Returns:
      the offset from the beginning of the file, in bytes, at which the next read or write occurs.
      Throws:
      IOException - if an I/O error occurs.
    • seek

      void seek(long pos) throws IOException
      Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs. The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.
      Notice: If you use getInputStream() you have to reget the InputStream after calling seek(long)
      Parameters:
      pos - the offset position, measured in bytes from the beginning of the file, at which to set the file pointer.
      Throws:
      IOException - if pos is less than 0 or if an I/O error occurs.
    • length

      long length() throws IOException
      Returns the length of this file.
      Returns:
      the length of this file, measured in bytes.
      Throws:
      IOException - if an I/O error occurs.
    • close

      void close() throws IOException
      Closes this random access file stream and releases any system resources associated with the stream. A closed random access file cannot perform input or output operations and cannot be reopened.

      If this file has an associated channel then the channel is closed as well.

      Throws:
      IOException - if an I/O error occurs.
    • getInputStream

      InputStream getInputStream() throws IOException
      get the input stream
      Notice: If you use seek(long) you have to reget the InputStream
      Throws:
      IOException
