- Method Detail
  - isLittleEndian
```
public boolean isLittleEndian()
```
    Determine whether this is a little-endian or big-endian alphabet.
    
    Returns:
    
    true if the alphabet is little-endian, false if it is big-endian
  - encode
```
public abstract int encode(int val)
```
    Encode the given byte value to a code point.
    
    Parameters:
    
    val - the value
    
    Returns:
    
    the Unicode code point
  - decode
```
public abstract int decode(int codePoint)
```
    Decode the given code point (character). If the code point is not valid, -1 is returned.
    
    Parameters:
    
    codePoint - the Unicode code point
    
    Returns:
    
    the decoded value or -1 if the code point is not valid
