getRange method
Parses the range values from the field at index index
.
When the range is multiline and is reading the first value, rangeEnd will be -1
and keepRanges will be true.
Implementation
void getRange(int index) {
final f = getField(index);
if (f.contains('..')) {
final parts = f.split('..');
rangeStart = _parseRune(parts[0]);
rangeEnd = _parseRune(parts[1]);
return;
}
final ini = _parseRune(f);
if (index == 0 && fields.length > 1 && fields[1].contains('First>')) {
rangeStart = ini;
rangeEnd = -1;
keepRanges = true;
return;
}
if (index == 0 && fields.length > 1 && fields[1].contains('Last>')) {
rangeEnd = ini;
keepRanges = false;
return;
}
rangeStart = rangeEnd = ini;
}
