toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
switch (this) {
case equals:
return '==';
case greaterThanOrEqual:
return '>=';
case lessThanOrEqual:
return '<=';
case greaterThan:
return '>';
case lessThan:
return '<';
case notEquals:
return '!=';
case inList:
return 'in';
case notInList:
return 'not in';
case like:
return 'like';
case notLike:
return 'not like';
case likeCs:
return 'like_cs';
case notLikeCs:
return 'not like_cs';
}
}
