/**
* The Range class defines continuous range of character.
*
*
The pair (startLine, startChar) defines the first character in the range. The pair (endLine,
* endChar) defines the first character AFTER the range (i.e. it doesn't belong the range).
* (endLine, endChar) must be a valid character inside text, except EOF case.
*
*
Special cases:
*
*
* - Zero length range: (startLine, startChar) = (endLine, endChar). Range defines insert
* position right before the (startLine, startChar) character (for {@link FixReplacement})
*
- EOF case - range includes the last character in the file:
*
* - if a file ends with EOL mark, then (endLine, endChar) = (num_of_lines + 1, 0)
*
- if a file doesn't end with EOL mark, then (endLine, endChar) = (num_of_lines,
* num_of_chars_in_last_line)
