Examples of java.io.BufferedInputStream.skip()

java.io.BufferedInputStream.skip()
See the general contract of the skip method of InputStream. @exception IOException if the stream does not support seek,or if this input stream has been closed by invoking its {@link #close()} method, or anI/O error occurs.

    /**
     * @tests java.io.BufferedInputStream#skip(long)
     */
    public void test_skip_NullInputStream() throws IOException {
        BufferedInputStream buf = new BufferedInputStream(null, 5);
        assertEquals(0, buf.skip(0));
    }


    /**
     * Sets up the fixture, for example, open a network connection. This method
     * is called before a test is executed.
