Examples of io.netty.buffer.ByteBuf.readInt()

io.netty.buffer.ByteBuf.readInt()
Gets a 32-bit integer at the current {@code readerIndex}and increases the {@code readerIndex} by {@code 4} in this buffer. @throws IndexOutOfBoundsException if {@code this.readableBytes} is less than {@code 4}

    public void testPrependAdjustedLength() throws Exception {
        final EmbeddedChannel ch = new EmbeddedChannel(new LengthFieldPrepender(4, -1));
        ch.writeOutbound(msg);
        ByteBuf buf = ch.readOutbound();
        assertEquals(4, buf.readableBytes());
        assertEquals(msg.readableBytes() - 1, buf.readInt());
        buf.release();


        buf = ch.readOutbound();
        assertSame(buf, msg);
        buf.release();
