translate

public int translate(CharSequence input,
                     int index,

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 reliable ignore StringWriter IOExceptions.

translate in class CharSequenceTranslator
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
