Examples of java.io.CharArrayReader

java.io.CharArrayReader
CharArrayReader is used as a buffered character input stream on a character array.

        deleteDb("lob");
        Connection conn;
        conn = reconnect(null);
        conn.createStatement().execute("CREATE TABLE TEST(ID IDENTITY, C CLOB)");
        PreparedStatement prep = conn.prepareStatement("INSERT INTO TEST(C) VALUES(?)");
        prep.setCharacterStream(1, new CharArrayReader("Bohlen".toCharArray()), "Bohlen".length());
        prep.execute();
        prep.setCharacterStream(1, new CharArrayReader("B\u00f6hlen".toCharArray()), "B\u00f6hlen".length());
        prep.execute();
        prep.setCharacterStream(1, getRandomReader(501, 1), -1);
        prep.execute();
        prep.setCharacterStream(1, getRandomReader(1501, 2), 401);
        prep.execute();
        conn = reconnect(conn);
        ResultSet rs = conn.createStatement().executeQuery("SELECT * FROM TEST ORDER BY ID");
        rs.next();
        assertEquals("Bohlen", rs.getString("C"));
        assertEqualReaders(new CharArrayReader("Bohlen".toCharArray()), rs.getCharacterStream("C"), -1);
        rs.next();
        assertEqualReaders(new CharArrayReader("B\u00f6hlen".toCharArray()), rs.getCharacterStream("C"), -1);
        rs.next();
        assertEqualReaders(getRandomReader(501, 1), rs.getCharacterStream("C"), -1);
        Clob clob = rs.getClob("C");
        assertEqualReaders(getRandomReader(501, 1), clob.getCharacterStream(), -1);
        assertEquals(501, clob.length());
