Interface TextWidthCounter

All Known Implementing Classes:

ASCIITextWidthCounter, CJKTextWidthCounter

public interface TextWidthCounter

This interface abstracts the way of counting text width.

Since argparse4j is command line argument parser package and it is intended to be used in terminal emulator and the terminal emulator in general uses fixed width fonts, the meaning of "width" here is given text consumes how many fixed character width. For string consisting only with ascii latin characters, it will be the same as the number of characters in given text. But for CJK characters are concerned this is not the case.
