29 * This abstract class is the superclass of all classes representing
30 * an output stream of bytes. An output stream accepts output bytes
31 * and sends them to some sink.
33 * Applications that need to define a subclass of
34 * <code>OutputStream</code> must always provide at least a method
35 * that writes one byte of output.

46 public abstract class OutputStream implements Closeable, Flushable {
48 * Writes the specified byte to this output stream. The general
49 * contract for <code>write</code> is that one byte is written
50 * to the output stream. The byte to be written is the eight
51 * low-order bits of the argument <code>b</code>. The 24
52 * high-order bits of <code>b</code> are ignored.
54 * Subclasses of <code>OutputStream</code> must provide an
55 * implementation for this method.
57 * @param b the <code>byte</code>.
58 * @exception IOException if an I/O error occurs. In particular,
59 * an <code>IOException</code> may be thrown if the
60 * output stream has been closed.
62 public abstract void write(int b) throws IOException;
65 * Writes <code>b.length</code> bytes from the specified byte array
66 * to this output stream. The general contract for <code>write(b)</code>
67 * is that it should have exactly the same effect as the call
68 * <code>write(b, 0, b.length)</code>.
71 * @exception IOException if an I/O error occurs.
72 * @see java.io.OutputStream#write(byte[], int, int)
74 public void write(byte b[]) throws IOException {
75 write(b, 0, b.length);
79 * Writes <code>len</code> bytes from the specified byte array
80 * starting at offset <code>off</code> to this output stream.
81 * The general contract for <code>write(b, off, len)</code> is that
82 * some of the bytes in the array <code>b</code> are written to the
83 * output stream in order; element <code>b[off]</code> is the first
84 * byte written and <code>b[off+len-1]</code> is the last byte written
87 * The <code>write</code> method of <code>OutputStream</code> calls
88 * the write method of one argument on each of the bytes to be
89 * written out. Subclasses are encouraged to override this method and
90 * provide a more efficient implementation.
92 * If <code>b</code> is <code>null</code>, a
93 * <code>NullPointerException</code> is thrown.
95 * If <code>off</code> is negative, or <code>len</code> is negative, or
96 * <code>off+len</code> is greater than the length of the array
97 * <code>b</code>, then an <tt>IndexOutOfBoundsException</tt> is thrown.
100 * @param off the start offset in the data.
101 * @param len the number of bytes to write.
102 * @exception IOException if an I/O error occurs. In particular,
103 * an <code>IOException</code> is thrown if the output
106 public void write(byte b[], int off, int len) throws IOException {
108 throw new NullPointerException();

121 * Flushes this output stream and forces any buffered output bytes
122 * to be written out. The general contract of <code>flush</code> is
123 * that calling it is an indication that, if any bytes previously
124 * written have been buffered by the implementation of the output
125 * stream, such bytes should immediately be written to their
126 * intended destination.
128 * If the intended destination of this stream is an abstraction provided by
129 * the underlying operating system, for example a file, then flushing the
130 * stream guarantees only that bytes previously written to the stream are
131 * passed to the operating system for writing; it does not guarantee that
132 * they are actually written to a physical device such as a disk drive.
134 * The <code>flush</code> method of <code>OutputStream</code> does nothing.
136 * @exception IOException if an I/O error occurs.
138 public void flush() throws IOException {
142 * Closes this output stream and releases any system resources
143 * associated with this stream. The general contract of <code>close</code>
144 * is that it closes the output stream. A closed stream cannot perform
145 * output operations and cannot be reopened.
147 * The <code>close</code> method of <code>OutputStream</code> does nothing.
149 * @exception IOException if an I/O error occurs.
