Constructor Detail

SeekableOutputStream

public SeekableOutputStream(java.io.RandomAccessFile file)

Constructs a SeekableOutputStream from a RandomAccessFile. Unless otherwise indicated, all method invocations are fowarded to the underlying RandomAccessFile.

Method Detail

write

public void write(int b)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method writes a single byte to the output stream. The byte written is the low eight bits of the int passed and a argument.

Subclasses must provide an implementation of this abstract method

---

write

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

Description copied from class: java.io.OutputStream

This method all the writes bytes from the passed array to the output stream. This method is equivalent to write(b, 0, buf.length) which is exactly how it is implemented in this class.

---

write

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

Description copied from class: java.io.OutputStream

This method writes len bytes from the specified array b starting at index off into the array.

This method in this class calls the single byte write() method in a loop until all bytes have been written. Subclasses should override this method if possible in order to provide a more efficent implementation.

---

flush

public void flush()
           throws java.io.IOException

Invokes getFD().sync() on the underlying RandomAccessFile.

---

close

public void close()
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method closes the stream. Any internal or native resources associated with this stream are freed. Any subsequent attempt to access the stream might throw an exception.

This method in this class does nothing.

---

getFilePointer

public long getFilePointer()
                    throws java.io.IOException

---

seek

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