ByteSequence

```
public interface ByteSequence
```
A ByteSequence is a readable sequence of byte values. This interface provides uniform, read-only access to many different kinds of byte sequences.
This interface does not refine the general contracts of the equals and hashCode methods. The result of comparing two objects that implement ByteSequence is therefore, in general, undefined. Each object may be implemented by a different class, and there is no guarantee that each class will be capable of testing its instances for equality with those of the other. It is therefore inappropriate to use arbitrary ByteSequence instances as elements in a set or as keys in a map.

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`byte`	`byteAt(int index)` Returns the `byte` value at the specified index.
`default IntStream`	`bytes()` Returns a stream of `int` zero-extending the `byte` values from this sequence.
`static ByteSequence`	`create(byte[] buffer)` Creates a `ByteSequence` from an existing `byte[]`.
`int`	`length()` Returns the length of this byte sequence.
`default ByteSequence`	`subSequence(int startIndex, int endIndex)` Returns a `ByteSequence` that is a subsequence of this sequence.
`default byte[]`	`toByteArray()` Returns a `byte[]` containing the bytes in this sequence in the same order as this sequence.

  - length
```
int length()
```
    Returns the length of this byte sequence.
    
    Returns:
    
    the number of bytes in this sequence

  - byteAt
```
byte byteAt(int index)
```
    Returns the byte value at the specified index. An index ranges from zero to length() - 1. The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.
    
    Parameters:
    
    index - the index of the byte value to be returned
    
    Returns:
    
    the specified byte value
    
    Throws:
    
    IndexOutOfBoundsException - if the index argument is negative or not less than length()

  - subSequence
```
default ByteSequence subSequence(int startIndex,
                                 int endIndex)
```
    Returns a ByteSequence that is a subsequence of this sequence. The subsequence starts with the byte value at the specified index and ends with the byte value at index end - 1. The length (in bytes) of the returned sequence is end - start, so if start == end then an empty sequence is returned.
    
    Parameters:
    
    startIndex - the start index, inclusive
    
    endIndex - the end index, exclusive
    
    Returns:
    
    the specified subsequence
    
    Throws:
    
    IndexOutOfBoundsException - if start or end are negative, if end is greater than length(), or if start is greater than end

  - toByteArray
```
default byte[] toByteArray()
```
    Returns a byte[] containing the bytes in this sequence in the same order as this sequence. The length of the byte array will be the length of this sequence. Creates a new byte array with every invocation.
    
    Since:
    
    19.0
  - bytes
```
default IntStream bytes()
```
    Returns a stream of int zero-extending the byte values from this sequence.
    
    Returns:
    
    an IntStream of byte values from this sequence
    
    Since:
    
    19.0
  - create
```
static ByteSequence create(byte[] buffer)
```
    Creates a ByteSequence from an existing byte[]. The byte array is not defensively copied, therefore the given bytes must not mutate to ensure the contract of an immutable ByteSequence.
