write
public void write(int)
throws IOException
- Description copied from class:
OutputStream
- Writes the specified byte to this output stream. The general
contract for
write
is that one byte is written
to the output stream. The byte to be written is the eight
low-order bits of the argument b
. The 24
high-order bits of b
are ignored.
Subclasses of OutputStream
must provide an
implementation for this method.
- Overrides:
write
in class FilterOutputStream
- Parameters:
- the byte
.
- Throws:
IOException
- if an I/O error occurs. In particular,
an IOException
may be thrown if the
output stream has been closed.
write
public void write(byte[],
int,
int)
throws IOException
- Description copied from class:
OutputStream
- Writes
len
bytes from the specified byte array
starting at offset off
to this output stream.
The general contract for write(b, off, len)
is that
some of the bytes in the array b
are written to the
output stream in order; element b[off]
is the first
byte written and b[off+len-1]
is the last byte written
by this operation.
The write
method of OutputStream
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
is null
, a
NullPointerException
is thrown.
If off
is negative, or len
is negative, or
off+len
is greater than the length of the array
b
, then an IndexOutOfBoundsException is thrown.
- Overrides:
write
in class FilterOutputStream
- Parameters:
- the data.
- the start offset in the data.
- the number of bytes to write.
- Throws:
IOException
- if an I/O error occurs. In particular,
an IOException
is thrown if the output
stream is closed.
flush
public void flush()
throws IOException
- Description copied from class:
OutputStream
- Flushes this output stream and forces any buffered output bytes
to be written out. The general contract of
flush
is
that calling it is an indication that, if any bytes previously
written have been buffered by the implementation of the output
stream, such bytes should immediately be written to their
intended destination.
The flush
method of OutputStream
does nothing.
- Overrides:
flush
in class FilterOutputStream
- Throws:
IOException
- if an I/O error occurs.
