```
public ByteArrayDataInputStream advance(int amount)
```
    Advances the current position without reading any bytes. This can be useful to skip bytes if necessary or if the byte[] is read externally from this InputStream.
    
    Parameters:
    
    amount - the amount to move the position forward
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if the amount to move and the current position is larger than the limit
  - read
```
public int read()
```
    Reads the next byte of data from buf. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the buffer has been reached, the value -1 is returned.
    
    Specified by:
    
    read in class java.io.InputStream
    
    Returns:
    
    the next byte of data, or -1 if the end of the stream has been reached.
  - read

public int read(byte[] b,
                int off,

  - readBuffer
```
public java.nio.ByteBuffer readBuffer(int len)
```
    Non-copying reading of len bytes from the input stream into a ByteBuffer.
    Reads len bytes from the input stream and wraps them in a ByteBuffer. Note that the buffer is pinned to a subrange of the underlying 'buf' byte[] array: make sure that the contents of 'buf' don't change until you're done with 'buf', or else you'll end up with unpredictable behavior.
