Examples of org.apache.hadoop.io.InputBuffer

org.apache.hadoop.io.InputBuffer
A reusable {@link InputStream} implementation that reads from an in-memorybuffer.
This saves memory over creating a new InputStream and ByteArrayInputStream each time data is read.
Typical usage is something like the following:
```
 InputBuffer buffer = new InputBuffer(); while (... loop condition ...) { byte[] data = ... get data ...; int dataLength = ... get data length ...; buffer.reset(data, dataLength); ... read buffer using InputStream methods ... } 
```

     * @throws Exception if failed
     */
    @Test
    public void readByte_random() throws Exception {
        byte[] bytes = "ABC|D|EF".getBytes(Charset.forName("ASCII"));
        InputBuffer buffer = new InputBuffer();
        buffer.reset(bytes, bytes.length);
        Random random = new Random(12345);
        for (int i = 0; i < 100000; i++) {
            int[] bounds = new int[5];
            for (int j = 0; j < bounds.length; j++) {
                bounds[j] = random.nextInt(bytes.length + 1);
