Constructor Detail

AppleDouble

AppleDouble(java.io.File file,
            java.lang.String mode)
      throws java.io.IOException

Method Detail

writeFinderInfo

public void writeFinderInfo(byte[] b)
                     throws java.io.IOException

---

readFinderInfo

public void readFinderInfo(byte[] b)
                    throws java.io.IOException

---

realSeek

public void realSeek(long off)
              throws java.io.IOException

---

realLength

public long realLength()
                throws java.io.IOException

---

seek

public void seek(long off)
          throws java.io.IOException

Description copied from class: java.io.RandomAccessFile

This method sets the current file position to the specified offset from the beginning of the file. Note that some operating systems will allow the file pointer to be set past the current end of the file.

---

length

public long length()
            throws java.io.IOException

Description copied from class: java.io.RandomAccessFile

This method returns the length of the file in bytes

---

write

public void write(byte[] data,
                  int off,
                  int len)
           throws java.io.IOException

Description copied from class: java.io.RandomAccessFile

This method writes len bytes to the file from the specified array starting at index offset into the array.

---

setLength

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

Description copied from class: java.io.RandomAccessFile

This method sets the length of the file to the specified length. If the currently length of the file is longer than the specified length, then the file is truncated to the specified length (the file position is set to the end of file in this case). If the current length of the file is shorter than the specified length, the file is extended with bytes of an undefined value (the file position is unchanged in this case).

The file must be open for write access for this operation to succeed.

---

close

public void close()
           throws java.io.IOException

Description copied from class: java.io.RandomAccessFile

This method closes the file and frees up all file related system resources. Since most operating systems put a limit on how many files may be opened at any given time, it is a good idea to close all files when no longer needed to avoid hitting this limit
