compareTo method
Compares this object to another object.
Returns a value like a Comparator when comparing this
to other
.
That is, it returns a negative integer if this
is ordered before other
,
a positive integer if this
is ordered after other
,
and zero if this
and other
are ordered together.
The other
argument must be a value that is comparable to this object.
Implementation
@override
int compareTo(TableConstraint other) {
var cmp = priority.compareTo(other.priority);
if (cmp == 0) {
cmp = field.compareTo(other.field);
}
return cmp;
}
