This class provides a sequential OutputStream wrapper around a RandomAccessFile.
Note that closing this object does not close the wrapped RandomAccessFile.

Method Details

write
Writes the specified byte to this output stream. The general contract forwrite
is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argumentb
. The 24 high-order bits ofb
are ignored.Subclasses of
OutputStream
must provide an implementation for this method.- Specified by:
write
in classOutputStream
- Parameters:
b
- thebyte
.- Throws:
IOException
- if an I/O error occurs. In particular, anIOException
may be thrown if the output stream has been closed.
-
write
Writesb.length
bytes from the specified byte array to this output stream. The general contract forwrite(b)
is that it should have exactly the same effect as the callwrite(b, 0, b.length)
.- Overrides:
write
in classOutputStream
- Parameters:
b
- the data.- Throws:
IOException
- if an I/O error occurs.- See Also:
-
write
Writeslen
bytes from the specified byte array starting at offsetoff
to this output stream. The general contract forwrite(b, off, len)
is that some of the bytes in the arrayb
are written to the output stream in order; elementb[off]
is the first byte written andb[off+len-1]
is the last byte written by this operation.The
write
method ofOutputStream
calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.If
b
isnull
, aNullPointerException
is thrown.If
off
is negative, orlen
is negative, oroff+len
is greater than the length of the arrayb
, then anIndexOutOfBoundsException
is thrown.- Overrides:
write
in classOutputStream
- Parameters:
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.- Throws:
IOException
- if an I/O error occurs. In particular, anIOException
is thrown if the output stream is closed.
