```
public abstract class CharSequenceTranslator
extends Object
```
An API for translating text. Its core use is to escape and unescape text. Because escaping and unescaping is completely contextual, the API does not present two separate signatures.

  - translate
```
public abstract int translate(CharSequence input,
            int index,
            Writer out)
                       throws IOException
```
    Translate a set of codepoints, represented by an int index into a CharSequence, into another set of codepoints. The number of codepoints consumed must be returned, and the only IOExceptions thrown must be from interacting with the Writer so that the top level API may reliably ignore StringWriter IOExceptions.
    
    Parameters:
    input - CharSequence that is being translated
    index - int representing the current point of translation
    out - Writer to translate the text to
    
    Returns:
    int count of codepoints consumed
    
    Throws:
    
    IOException - if and only if the Writer produces an IOException
  - translate
```
public final String translate(CharSequence input)
```
    Helper for non-Writer usage.
    
    Parameters:
    input - CharSequence to be translated
    
    Returns:
    String output of translation
  - translate
```
public final void translate(CharSequence input,
             Writer out)
                     throws IOException
```
    Translate an input onto a Writer. This is intentionally final as its algorithm is tightly coupled with the abstract method of this class.
    
    Parameters:
    input - CharSequence that is being translated
    out - Writer to translate the text to
    
    Throws:
    
    IOException - if and only if the Writer produces an IOException
  - with
```
public final CharSequenceTranslator with(CharSequenceTranslator... translators)
```
    Helper method to create a merger of this translator with another set of translators. Useful in customizing the standard functionality.
    
    Parameters:
    translators - CharSequenceTranslator array of translators to merge with this one
    
    Returns:
    CharSequenceTranslator merging this translator with the others
  - hex
```
public static String hex(int codepoint)
```
    Returns an upper case hexadecimal String for the given character.
    
    Parameters:
    codepoint - The codepoint to convert.
    
    Returns:
    An upper case hexadecimal String
