All Implemented Interfaces:
Serializable, Comparable<ByteArray>
Direct Known Subclasses:
MsgID, Token
```
public class ByteArray
extends Object
implements Serializable, Comparable<ByteArray>

Constructor and Description
`ByteArray()` Creates an empty ByteArray.
`ByteArray(byte[] data)` Sets valid = data.length, unless data is null Sets offset = 0
`ByteArray(byte[] data, int offset, int length)` Sets offset = offset Sets valid = length

- Constructor Detail
  - ByteArray
```
public ByteArray()
```
    Creates an empty ByteArray.
  - ByteArray
```
public ByteArray(byte[] data)
```
    Sets valid = data.length, unless data is null Sets offset = 0
    Parameters:
    data - the byte array, may be null
  - ByteArray
```
public ByteArray(byte[] data,
                 int offset,
                 int length)
```
    Sets offset = offset Sets valid = length
    Parameters:
    data - the byte array, may be null but why would you do that
    offset - the starting offset
    length - the valid length
- Method Detail
  - compareTo
```
public final int compareTo(ByteArray ba)
```
    Compares this ByteArray with another ByteArray.
    Specified by:
    compareTo in interface Comparable<ByteArray>
  - equals
```
public final boolean equals(Object o)
```
    Compares this ByteArray with another object for equality.
    Overrides:
    equals in class Object
  - getData
```
public byte[] getData()
```
    Returns the underlying byte array.
    Returns:
    the data
  - getOffset
```
public int getOffset()
```
    Returns the offset into the byte array.
    Returns:
    the offset
  - getValid
```
public int getValid()
```
    Count how many of the bytes in the array are 'valid'. this property does not necessarily have meaning for all byte arrays.
    Returns:
    the number of valid bytes
  - hashCode
```
public final int hashCode()
```
    Hash code based on the underlying byte array data.
    Overrides:
    hashCode in class Object
  - setData
```
public void setData(byte[] data)
```
    Sets the underlying byte array. Warning, does not set valid
    Parameters:
    data - the new byte array
  - setOffset
```
public void setOffset(int offset)
```
    Sets the offset into the byte array.
    Parameters:
    offset - the new offset
  - setValid
```
public void setValid(int valid)
```
    Sets the number of valid bytes.
    Parameters:
    valid - the new valid count
  - toBase64
```
public final String toBase64()
```
    Returns this ByteArray as a Base64 encoded string.
    Returns:
    the Base64 encoded string
  - toString
```
public String toString()
```
    Returns a string representation of this ByteArray.
    Overrides:
    toString in class Object
