Appendable (Codename One API)

All Known Implementing Classes:

StringWriter
```
public interface Appendable
```
Declares methods to append characters or character sequences. Any class that implements this interface can receive data formatted by a java.util.Formatter. The appended character or character sequence should be valid according to the rules described in Unicode Character Representation.
Appendable itself does not guarantee thread safety. This responsibility is up to the implementing class.
Implementing classes can choose different exception handling mechanism. They can choose to throw exceptions other than IOException or they do not throw any exceptions at all and use error codes instead.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`Appendable`	`append(char c)` Appends the specified character.
`Appendable`	`append(CharSequence csq)` Appends the character sequence `csq`.
`Appendable`	`append(CharSequence csq, int start, int end)` Appends a subsequence of `csq`.

- Method Detail
  - append
```
Appendable append(char c)
           throws IOException
```
    Appends the specified character.
    
    Parameters:
    
    c - the character to append.
    
    Returns:
    
    this Appendable.
    
    Throws:
    
    IOException - if an I/O error occurs.
  - append
```
Appendable append(CharSequence csq)
           throws IOException
```
    Appends the character sequence csq. Implementation classes may not append the whole sequence, for example if the target is a buffer with limited size.
    If csq is null, the characters "null" are appended.
    
    Parameters:
    
    csq - the character sequence to append.
    
    Returns:
    
    this Appendable.
    
    Throws:
    
    IOException - if an I/O error occurs.
  - append
```
Appendable append(CharSequence csq,
                  int start,
                  int end)
           throws IOException
```
    Appends a subsequence of csq.
    If csq is not null then calling this method is equivalent to calling append(csq.subSequence(start, end)).
    If csq is null, the characters "null" are appended.
    
    Parameters:
    
    csq - the character sequence to append.
    
    start - the first index of the subsequence of csq that is appended.
    
    end - the last index of the subsequence of csq that is appended.
    
    Returns:
    
    this Appendable.
    
    Throws:
    
    IndexOutOfBoundsException - if start < 0, end < 0, start > end or end is greater than the length of csq.
    
    IOException - if an I/O error occurs.
