Observation class final Getting started

A single scalar measurement at a point in time.

time is a plain double in the caller's own unit, and the components' process variances are expressed per that unit. The default search brackets in fit suit days; TimeAxis converts calendar dates to days.

Implemented types

• Comparable<Observation>

Constructors

Observation(double time, double value, {double relativeVariance = 1.0})

A reading of value taken at time.

const

Properties

hashCode → int

The hash code for this object.

no setter, override

relativeVariance → double

Noise variance of this reading relative to the model's measurement variance, so the effective noise is relativeVariance * model.measurementVariance.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

time → double

When the reading was taken, in the caller's own time unit.

final

value → double

What was read.

final

Methods

compareTo(Observation other) → int

Compares this object to another object.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
