differenceEncoded static method
Returns the number of characters that are the same in the e1
and e2
encoded strings.
Despite the name, this is actually a measure of similarity.
This naming is consistent with the SQL DIFFERENCE
function definition.
Implementation
static int differenceEncoded(final String? e1, final String? e2) {
if (e1 == null || e1.isEmpty || e2 == null || e2.isEmpty) {
return 0;
}
var iterator1 = e1.codeUnits.iterator;
var iterator2 = e2.codeUnits.iterator;
var diff = 0;
while (iterator1.moveNext() && iterator2.moveNext()) {
if (iterator1.current == iterator2.current) {
diff++;
}
}
return diff;
}
