#1 coordinate of the matched pattern
I know you are working on 'Named Groups', but i wanted
to display how i managed to retrieve coordinates of the
matched pattern with your current implementation. Your
implementation has catched my eye becouse it works
seamless on streams, which is very useful for the
linked string buffer i'm implementing (string
concatenation is generally much faster without the
realloc overhead).
Attached is the the LinkedStringBuffer utilizing the
new method.
