```
public final class ByteArrayBuilder
extends Object
```
Byte array builder class encodes data into byte arrays to send messages over the replication protocol. Built on top of ByteStringBuilder, it isolates the latter against legacy type conversions from the replication protocol. It exposes a fluent API.

ByteArrayScanner class that decodes messages built with current class.

public ByteArrayBuilder appendZeroTerminatedByteArray(byte[] bytes)
```
    Append all the bytes from the byte array to this ByteArrayBuilder and then append a final zero byte separator for compatibility with legacy implementations.
    Note: the super long method name it is intentional: nobody will want to use it, which is good because nobody should.

    Returns:
    
    this ByteArrayBuilder
  - appendServerStateMustComeLast
```
public ByteArrayBuilder appendServerStateMustComeLast(ServerState serverState)
```
    Append the byte representation of a ServerState to this ByteArrayBuilder and then append a final zero byte separator.
    Caution: ServerState MUST be the last field. Because ServerState can contain null character (string termination of replica id string ..) it cannot be decoded using ByteArrayScanner.nextString() like the other fields. The only way is to rely on the end of the input buffer: and that forces the ServerState to be the last field. This should be changed if we want to have more than one ServerState field.
    Note: the super long method name it is intentional: nobody will want to use it, which is good because nobody should.
    
    Parameters:
    
    serverState - the ServerState to append.
    
    Returns:
    
    this ByteArrayBuilder

    ByteArrayScanner.nextServerStateMustComeLast()

public byte[] toByteArray()
```

    the content of this ByteStringBuilder converted to a byte array.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - bytes
```
public static int bytes(int nbFields)
```
    Helper method that returns the number of bytes that would be used by the byte fields when appended to a ByteArrayBuilder.
    
    Parameters:
    
    nbFields - the number of byte fields that will be appended to a ByteArrayBuilder
    
    Returns:
    
    the number of bytes occupied by the appended byte fields.
  - shorts
```
public static int shorts(int nbFields)
```
    Helper method that returns the number of bytes that would be used by the short fields when appended to a ByteArrayBuilder.
    
    Parameters:
    
    nbFields - the number of short fields that will be appended to a ByteArrayBuilder
    
    Returns:
    
    the number of bytes occupied by the appended short fields.
  - csnsV1

```
    Helper method that returns the number of bytes that would be used by the CSN fields when appended to a ByteArrayBuilder.
    
    Parameters:
    
    nbFields - the number of CSN fields that will be appended to a ByteArrayBuilder
    
    Returns:
    
    the number of bytes occupied by the appended CSN fields.
