- Constructs a quantity range, from q1 to q2.
Properties
- centerValue → Q
-
The value at the center of the range.
no setter
- delta → Q
-
The change in value from start to end, which may be negative.
no setter
- hashCode → int
-
Two equal quantity ranges will have the same hash code.
no setteroverride
- maxValue → Q
-
The maximum value in this range.
no setter
- minValue → Q
-
The minimum value in this range.
no setter
- q1 ↔ Q
-
The starting quantity of the range.
getter/setter pair
- q2 ↔ Q
-
The ending quantity of the range.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
contains(
Q quantity, [bool inclusive = true, double epsilon = 1.0e-10]) → bool -
True if this range contains
quantity, with a tolerance,epsilon, of rounding errors of 1.0e-10 andinclusiveof the endpoints by default. -
encompasses(
QuantityRange< Q> range2) → bool - True only if this range completely encompasses range2.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
overlaps(
QuantityRange< Q> range2) → bool -
Returns true if this range overlaps
range2(exclusive of the endpoints). -
toString(
) → String -
Returns a String representation of this range in the form '
override
Operators
-
operator ==(
dynamic obj) → bool -
Two quantity ranges are considered equal only if their endpoints are exactly equal.
