Method Detail

translate

public int translate(CharSequence input,
                     int index,
                     Writer out)
              throws IOException

The first translator to consume codepoints from the input is the 'winner'. Execution stops with the number of consumed codepoints being returned. 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 reliable ignore StringWriter IOExceptions.

Specified by:

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
