Frequency(double amount, MeasurementInterpreter<
Frequency> interpreter, [Precision precision = Precision.max]) -
Constructs a Frequency.

Properties
-
defaultInterpreter
→ MeasurementInterpreter<
Frequency> ? -

-
Returns
true
if this measurement is finite.no setterinherited - isInfinite → bool

if this measurement is infinite (either positive or negative).no setterinherited - isNaN → bool
-
Returns
true
if this measurement cannot be expressed as a number.no setterinherited - isNegative → bool

Methods
-
acceptVisitor(
MeasurementVisitor visitor) → void -
Accept a visitor object for double-dispatch.
override
-
as(
MeasurementInterpreter< Frequency> interpreter) → double - Interprets this using the specified units.
-
by<
V extends Measurement< (V> >Measurement< V> other) → DerivedMeasurement<Measurement< Frequency> , Measurement<V> > -
Creates a derived unit that is the multiplication of this measurement with another.
inherited
-
compareMagnitude(
Frequency other) → double -
Returns the difference in magnitude between this and another measurement.
inherited
-
compareTo(
Frequency other) → int -
Compares this object to another object.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
per<
V extends Measurement< (V> >Measurement< V> other) → DerivedMeasurement<Measurement< Frequency> , Measurement<V> > -
Creates a derived measurement that is the division of this measurement with another.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
withDefaultUnit(
MeasurementInterpreter< Frequency> interpreter) → Frequency -
Creates a new measurement equivalent to this one but with a different
default unit.
inherited
-
withPrecision(
Precision precision) → Frequency -
Creates an equivalent measurement with the specified precision.
inherited
