Bytes

```
@Immutable
public final class Bytes
extends java.lang.Object
```
Immutable Wrapper around a byte array.
Wrap a bytearray so it prevents callers from modifying its contents. It does this by making a copy upon initialization, and also makes a copy if the underlying bytes are requested.

Since:

1.0.0

  - copyFrom
```
public static Bytes copyFrom(byte[] data)
```
    Parameters:
    
    data - the byte array to be wrapped.
    
    Returns:
    
    an immutable wrapper around the provided bytes.
  - copyFrom
```
public static Bytes copyFrom(byte[] data,
                             int start,
                             int len)
```
    Wrap an immutable byte array over a slice of a Bytes
    
    Parameters:
    
    data - the byte array to be wrapped.
    
    start - the starting index of the slice
    
    len - the length of the slice. If start + len is larger than the size of data, the remaining data will be returned.
    
    Returns:
    
    an immutable wrapper around the bytes in the slice from start to start + len
  - toByteArray
