[victornoel]

@DmitryBarskov so one last check: did you validate that there were no more generic to update in the whole text package?

[DmitryBarskov]

@victornoel found some other parameters for generalizing. But I skipped some params when they are regular expressions. I think they should be string literals. WDYT?

[victornoel]

@DmitryBarskov sorry, I'm missing a bit of context: which one are you talking about that should be String instead of CharSequence?

[DmitryBarskov]

@victornoel I'm talking about ctor Split(final Text text, final String rgx, final int lmt). Do you think CharSequence is used for regular expressions?

[victornoel]

@DmitryBarskov I think it's not the responsibility of Split to know how its input are built, so yes, if we decide that the interface to use for string (not the java type, the concept) is CharSequence, then it should be used everywhere.

[victornoel]

@DmitryBarskov sorry for the late feedback, I didn't realize you made some changes :) don't hesitate to ping me if you don't get any updates in the future!
