Methods

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

Operators

operator *(double multiplier) → T
Returns a measurement equivalent to a multiple of this.
operator +(T other) → T
Returns a measurement equivalent to the sum of two others.
operator -(T other) → T
Returns a measurement equivalent to the difference between two others.
operator /(double divisor) → T
Returns a measurement equivalent to a fraction of this.
operator <(T other) → bool
Returns true if this is less than the other measurement.
operator <=(T other) → bool
Returns true if this is less than or equal to the other measurement.
operator ==(Object other) → bool
The equality operator.
override
operator >(T other) → bool
Returns true if this is greater than the other measurement.
operator >=(T other) → bool
Returns true if this is greater than or equal to the other measurement.
operator unary-() → T
Returns a measurement representing the opposite of this.
operator ~/(T other) → int
Returns the truncating division result of this and another measurement.
