Detailed Description

A class that intercepts and mirrors lookup operations on charsets.

This class shadows the []-based lookup operations in Charset and causes all instances of braille cell dots to be mirrored about the vertical axis. Useful for the Braille Tutor itself, where users must enter the mirror image of Braille dots into the slate cells.

[inline, static]

Mirrors the positions of Braille dots around the vertical axis.

Returns a new dot pattern with dots 1,2,3 swapped with dots 4,5,6 and dot 7 swapped with dot 8. Useful for the Braille Tutor itself, where users must enter the mirror image of Braille dots into the slate cells.
